==Power==

The board takes fixed 5V input, (with the 1V2 core voltage generated directly from the input using the internal switch-mode supply on the BCM2835 die).
This permits adoption of the micro USB form factor, which, in turn, prevents the user from inadvertently plugging in out-of-range power inputs; that would be dangerous, since the 5V would go straight to HDMI and output USB ports, even though the problem should be mitigated by some protections applied to the input power: The board provides a polarity protection diode, a voltage clamp, and a self-resetting semiconductor fuse.

Premier Farnell recommend the following power supplies:
* Model A: 5V dc, 500-700mA
* Model B: 5V dc, 700-1200mA

Power consumption of the Raspberry Pi device is

* Board A: 5V, 500 mA (2.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI)
* Board B: 5V, 700 mA (3.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI) (Is this correct? These [http://www.raspberrypi.org/forum/troubleshooting/usb-hub-sending-power-to-raspberry-pi-through-usb-port/#p68382] links [http://www.raspberrypi.org/forum/general-discussion/raspberry-pi-power-requirements/page-2/#p68224] suggest that the 700mA is only required if "using networking and high-current USB peripherals" [http://www.raspberrypi.org/archives/260].)

You will need to provide a power supply that can provide enough current to power the device plus any connected peripherals, and taking into account inefficiencies of the supply itself and the cable between the power supply and Raspberry Pi. The community advises opting for a power supply that can supply at least 1A if using USB peripherals or Pi plates that draw more than a few tens of milliamps of current.

*As the 5V rail is brought out in the [[Rpi_Low-level_peripherals | GPIO pins]], you can power the Rpi from there too. You should mind however, that those are ''behind'' the power protection circuitry , so you should provide your own.
* It is possible to power the Rpi from a powered USB hub the Rpi controls, but only on 'dumb' devices, that allow the port to supply the full current without waiting for the usb device to ask for it[http://www.raspberrypi.org/forum/general-discussion/power-pi-from-usb-hub-connected-to-pi]. As the power input of the Rpi doesn't have its data leads connected, there is no chance for a communication loop of some sorts.
* POE ([http://nl.wikipedia.org/wiki/Power_over_Ethernet power over ethernet]) is currently not available for the Rpi (but nobody stops you from taking your soldering iron and doing it yourself)

===Power Supply Problems===

There have been a number of problems reported that seem to be caused by inadequate power, this is an attempt to explain what is needed and the consequences of not having enough power.

The power required by the Pi will vary depending on how busy it is and what peripherals are connected.
* Running a GUI will take more power.
* The USB devices and Ethernet connection will take power.
* Running software will take power.

This means that it's difficult to say exactly how much power is needed. People have reported current requirements of between 300mA and 550mA. But it could in reality take more, especially for short periods. A simple multimeter will not show short surges on the power requirement. A surge in the power requirement for a few milliseconds will not be detectable by a meter but will be enough to cause problems.
If the board does not get enough power the voltage will drop. If it drops enough parts of the system will run unreliably because data can get corrupted. The USB IC runs on 5V and handles the USB and Ethernet ports so it's likely that this will be the first thing to fail. Problems seen are unreliable Ethernet connection and unreliable operation of the Keyboard and/or mouse. Each USB port on the Pi has a fuse rated at 140 mA, so any connected USB devices should draw less than this amount of current. Some USB WiFi dongles are known to draw more than 150 mA when configured and active.

There are several reasons why the power to the board may be inadequate:
* The PSU may not deliver enough power. Although the maximum power requirement is said to be 700mA, that is with no peripherals connected (USB, Ethernet etc), so a 1000mA PSU should be regarded as a minimum. This allows some leeway in case the power supply cannot deliver it's full power without the voltage dropping.
* The PSU is not regulated.
* The cable connecting the PSU to the Pi may not be good. People have reported cables with 4 ohms resistance on the power connections. At 500mA drain this would reduce a 5V supply to 3V.

====How Can I tell if the power supply is inadequate?====

Common symptoms of an inadequate power supply are
* Unreliable Ethernet or keyboard operation, especially if it's OK at first but not when the GUI is started.
* SD card errors at start up seems to be another symptom of poor power.

If you think you have a problem with your power supply, it is a good idea to check the actual voltage
on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board
to facilitate voltage measurements.

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have a problem with your power supply or your power cable. Anything inside, but close to the limits, of this range ''may'' indicate a problem.

[[File:RPI_Test_Points.JPG|400px]] [[File:Voltmeter.JPG|250px]]

====Things that can cause problems====
* A USB connection on a TV or PC. The USB power supply specification is for up to 500mA and if the TV implements this then it can cause problems. The system may work initially but be unreliable because as it becomes more active the power requirement increases.
* A single supply from a powered hub. Most hubs seem to deliver more than the specified current but there's no guarantee. Check the power supply rating, it must be enough to supply everything that's connected to the hub.
* A power supply that is rated for less than 700mA may work some of the time.
* Adding a USB hard disk drive. A HDD will take quite a lot of power as it starts, maybe an amp or more. It the power supply for this also supplies the Pi then this could overload things and cause trouble.
* Some complex keyboards have been reported to take a considerable amount of power, maybe up to 500mA. The Pi cannot deliver this amount of power. Simpler budget keyboards may be better. If the system works with no keyboard attached but not with a keyboard then it's worth trying a different, simpler, keyboard.

====Summary====

* If you are having unreliable operation the first thing to do is check your power supply.
* Start with a good quality regulated power supply that is rated to provide 5V and at least 1A (1000mA).
* Use a good quality micro USB cable. Cables are notorious for giving trouble so be prepared to swap for another one.
* Not all power supplies will deliver what they claim.

===Capacitor C6===
Behind the microUSB power connector on the Model B is a metallic grey component called a capacitor, marked as C6. This capacitor helps stabilise the DC power on the board, but for some it has also become a place for their thumb when removing the RPI's power lead; unfortunately, this can result in the capacitor breaking off! It has been stated in the forums that the type of capacitor used for C6 will be changed on later RPi models for one with sturdier leads. If you do break off your C6 capacitor, it's highly likely that your RPi will still work properly, unless you have a particularly unstable power supply, but the general advice is to not use C6 as a leverage point when removing the power connector and also take care when storing or transporting your RPi if it's not fitted in a case - try not to stow the board where C6 could be knocked by other items - for example in a laptop carry case or in amongst some books.
[[File:Rpic6.jpg|300px|thumb|center|Capacitor C6 (ringed)]]

It's unlikely that replacing a broken off C6 capacitor will be covered under warranty, but fortunately they are easy to replace if you have average soldering skills, but remember that reworking your RPi will void its warranty too. C6 is a surface mount electrolytic capacitor, rated at 220uF 16V. The capacitor is polarised and so must be fitted the right way round - notice the black marking on one side in the picture above. A replacement capacitor can be purchased from numerous sources - for example:

==Power==

The board takes fixed 5V input, (with the 1V2 core voltage generated directly from the input using the internal switch-mode supply on the BCM2835 die).
This permits adoption of the micro USB form factor, which, in turn, prevents the user from inadvertently plugging in out-of-range power inputs; that would be dangerous, since the 5V would go straight to HDMI and output USB ports, even though the problem should be mitigated by some protections applied to the input power: The board provides a polarity protection diode, a voltage clamp, and a self-resetting semiconductor fuse.

Premier Farnell recommend the following power supplies:
* Model A: 5V dc, 500-700mA
* Model B: 5V dc, 700-1200mA

Power consumption of the Raspberry Pi device is

* Board A: 5V, 500 mA (2.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI)
* Board B: 5V, 700 mA (3.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI) (Is this correct? These [http://www.raspberrypi.org/forum/troubleshooting/usb-hub-sending-power-to-raspberry-pi-through-usb-port/#p68382] links [http://www.raspberrypi.org/forum/general-discussion/raspberry-pi-power-requirements/page-2/#p68224] suggest that the 700mA is only required if "using networking and high-current USB peripherals" [http://www.raspberrypi.org/archives/260].)

You will need to provide a power supply that can provide enough current to power the device plus any connected peripherals, and taking into account inefficiencies of the supply itself and the cable between the power supply and Raspberry Pi. The community advises opting for a power supply that can supply at least 1A if using USB peripherals or Pi plates that draw more than a few tens of milliamps of current.

*As the 5V rail is brought out in the [[Rpi_Low-level_peripherals | GPIO pins]], you can power the Rpi from there too. You should mind however, that those are ''behind'' the power protection circuitry , so you should provide your own.
* It is possible to power the Rpi from a powered USB hub the Rpi controls, but only on 'dumb' devices, that allow the port to supply the full current without waiting for the usb device to ask for it[http://www.raspberrypi.org/forum/general-discussion/power-pi-from-usb-hub-connected-to-pi]. As the power input of the Rpi doesn't have its data leads connected, there is no chance for a communication loop of some sorts.
* POE ([http://nl.wikipedia.org/wiki/Power_over_Ethernet power over ethernet]) is currently not available for the Rpi (but nobody stops you from taking your soldering iron and doing it yourself)

===Power Supply Problems===

There have been a number of problems reported that seem to be caused by inadequate power, this is an attempt to explain what is needed and the consequences of not having enough power.

The power required by the Pi will vary depending on how busy it is and what peripherals are connected.
* Running a GUI will take more power.
* The USB devices and Ethernet connection will take power.
* Running software will take power.

This means that it's difficult to say exactly how much power is needed. People have reported current requirements of between 300mA and 550mA. But it could in reality take more, especially for short periods. A simple multimeter will not show short surges on the power requirement. A surge in the power requirement for a few milliseconds will not be detectable by a meter but will be enough to cause problems.
If the board does not get enough power the voltage will drop. If it drops enough parts of the system will run unreliably because data can get corrupted. The USB IC runs on 5V and handles the USB and Ethernet ports so it's likely that this will be the first thing to fail. Problems seen are unreliable Ethernet connection and unreliable operation of the Keyboard and/or mouse. Each USB port on the Pi has a fuse rated at 140 mA, so any connected USB devices should draw less than this amount of current. Some USB WiFi dongles are known to draw more than 150 mA when configured and active.

There are several reasons why the power to the board may be inadequate:
* The PSU may not deliver enough power. Although the maximum power requirement is said to be 700mA, that is with no peripherals connected (USB, Ethernet etc), so a 1000mA PSU should be regarded as a minimum. This allows some leeway in case the power supply cannot deliver it's full power without the voltage dropping.
* The PSU is not regulated.
* The cable connecting the PSU to the Pi may not be good. People have reported cables with 4 ohms resistance on the power connections. At 500mA drain this would reduce a 5V supply to 3V.

====How Can I tell if the power supply is inadequate?====

Common symptoms of an inadequate power supply are
* Unreliable Ethernet or keyboard operation, especially if it's OK at first but not when the GUI is started.
* SD card errors at start up seems to be another symptom of poor power.

If you think you have a problem with your power supply, it is a good idea to check the actual voltage
on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board
to facilitate voltage measurements.

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have a problem with your power supply or your power cable. Anything inside, but close to the limits, of this range ''may'' indicate a problem.

[[File:RPI_Test_Points.JPG|400px]] [[File:Voltmeter.JPG|250px]]

====Things that can cause problems====
* A USB connection on a TV or PC. The USB power supply specification is for up to 500mA and if the TV implements this then it can cause problems. The system may work initially but be unreliable because as it becomes more active the power requirement increases.
* A single supply from a powered hub. Most hubs seem to deliver more than the specified current but there's no guarantee. Check the power supply rating, it must be enough to supply everything that's connected to the hub.
* A power supply that is rated for less than 700mA may work some of the time.
* Adding a USB hard disk drive. A HDD will take quite a lot of power as it starts, maybe an amp or more. It the power supply for this also supplies the Pi then this could overload things and cause trouble.
* Some complex keyboards have been reported to take a considerable amount of power, maybe up to 500mA. The Pi cannot deliver this amount of power. Simpler budget keyboards may be better. If the system works with no keyboard attached but not with a keyboard then it's worth trying a different, simpler, keyboard.

====Summary====

* If you are having unreliable operation the first thing to do is check your power supply.
* Start with a good quality regulated power supply that is rated to provide 5V and at least 1A (1000mA).
* Use a good quality micro USB cable. Cables are notorious for giving trouble so be prepared to swap for another one.
* Not all power supplies will deliver what they claim.

===Capacitor C6===
Behind the microUSB power connector on the Model B is a metallic grey component called a capacitor, marked as C6. This capacitor helps stabilise the DC power on the board, but for some it has also become a place for their thumb when removing the RPI's power lead; unfortunately, this can result in the capacitor breaking off! It has been stated in the forums that the type of capacitor used for C6 will be changed on later RPi models for one with sturdier leads. If you do break off your C6 capacitor, it's highly likely that your RPi will still work properly, unless you have a particularly unstable power supply, but the general advice is to not use C6 as a leverage point when removing the power connector and also take care when storing or transporting your RPi if it's not fitted in a case - try not to stow the board where C6 could be knocked by other items - for example in a laptop carry case or in amongst some books.
[[File:Rpic6.jpg|300px|thumb|center|Capacitor C6 (ringed)]]

It's unlikely that replacing a broken off C6 capacitor will be covered under warranty, but fortunately they are easy to replace if you have average soldering skills, but remember that reworking your RPi will void its warranty too. C6 is a surface mount electrolytic capacitor, rated at 200uF 16V. The capacitor is polarised and so must be fitted the right way round - notice the black marking on one side in the picture above. A replacement capacitor can be purchased from numerous sources - for example:

Although the maximum power requirement is said to be 700mA, that is with no peripherals connected (USB, Ethernet etc), so a 1000mA PSU should be regarded as a minimum. This allows some leeway in case the power supply cannot deliver it's full power without the voltage dropping.
* The PSU is not regulated.
* The cable connecting the PSU to the Pi may not be good. People have reported cables with 4 ohms resistance on the power connections. At 500mA drain this would reduce a 5V supply to 3V.

====How Can I tell if the power supply is inadequate?====

Common symptoms of an inadequate power supply are
* Unreliable Ethernet or keyboard operation, especially if it's OK at first but not when the GUI is started.
* SD card errors at start up seems to be another symptom of poor power.

If you think you have a problem with your power supply, it is a good idea to check the actual voltage
on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board
to facilitate voltage measurements.

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have a problem with your power supply or your power cable. Anything inside, but close to the limits, of this range ''may'' indicate a problem.

[[File:RPI_Test_Points.JPG|400px]] [[File:Voltmeter.JPG|250px]]

====Things that can cause problems====
* A USB connection on a TV or PC. The USB power supply specification is for up to 500mA and if the TV implements this then it can cause problems. The system may work initially but be unreliable because as it becomes more active the power requirement increases.
* A single supply from a powered hub. Most hubs seem to deliver more than the specified current but there's no guarantee. Check the power supply rating, it must be enough to supply everything that's connected to the hub.
* A power supply that is rated for less than 700mA may work some of the time.
* Adding a USB hard disk drive. A HDD will take quite a lot of power as it starts, maybe an amp or more. It the power supply for this also supplies the Pi then this could overload things and cause trouble.
* Some complex keyboards have been reported to take a considerable amount of power, maybe up to 500mA. The Pi cannot deliver this amount of power. Simpler budget keyboards may be better. If the system works with no keyboard attached but not with a keyboard then it's worth trying a different, simpler, keyboard.

====Summary====

* If you are having unreliable operation the first thing to do is check your power supply.
* Start with a good quality regulated power supply that is rated to provide 5V and at least 1A (1000mA).
* Use a good quality micro USB cable. Cables are notorious for giving trouble so be prepared to swap for another one.
* Not all power supplies will deliver what they claim.

===Capacitor C6===
Behind the microUSB power connector on the Model B board is a metallic grey component called a capacitor, marked as C6 on the board. This capacitor helps stabilise the DC power on the board, but for some it has also become a place for their thumb when removing the RPI's power lead; unfortunately, this can result in the capacitor breaking off the board. It has been stated in the forums that the type of capacitor used for C6 will be changed on later RPi models for one with sturdier leads. If you do break off your C6 capacitor, it's highly likely that your RPi will still work properly, unless you have a particularly unstable power supply, but the general advice is to not use C6 as a leverage point when removing the power connector and also take care when storing or transporting your RPi if it's not fitted in a case - try not to stow the board where C6 could be knocked by other items - for example in a laptop carry case or in amongst some books.
[[File:Rpic6.jpg|300px|thumb|center|Capacitor C6 (ringed)]]

It's unlikely that replacing a broken off C6 capacitor will be covered under warranty, but fortunately they are easy to replace if you have average soldering skills, but remember that reworking your RPi will void its warranty too. C6 is a surface mount electrolytic capacitor, rated at 200uF 16V. The capacitor is polarised and so must be fitted the right way round - notice the black marking on one side in the picture above. A replacement capacitor can be purchased from numerous sources - for example:

==Power==

The board takes fixed 5V input, (with the 1V2 core voltage generated directly from the input using the internal switch-mode supply on the BCM2835 die).
This permits adoption of the micro USB form factor, which, in turn, prevents the user from inadvertently plugging in out-of-range power inputs; that would be dangerous, since the 5V would go straight to HDMI and output USB ports, even though the problem should be mitigated by some protections applied to the input power: The board provides a polarity protection diode, a voltage clamp, and a self-resetting semiconductor fuse.

Premier Farnell recommend the following power supplies:
* Model A: 5V dc, 500-700mA
* Model B: 5V dc, 700-1200mA

Power consumption of the Raspberry Pi device is

* Board A: 5V, 500 mA (2.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI)
* Board B: 5V, 700 mA (3.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI) (Is this correct? These [http://www.raspberrypi.org/forum/troubleshooting/usb-hub-sending-power-to-raspberry-pi-through-usb-port/#p68382] links [http://www.raspberrypi.org/forum/general-discussion/raspberry-pi-power-requirements/page-2/#p68224] suggest that the 700mA is only required if "using networking and high-current USB peripherals" [http://www.raspberrypi.org/archives/260].)

You will need to provide a power supply that can provide enough current to power the device plus any connected peripherals, and taking into account inefficiencies of the supply itself and the cable between the power supply and Raspberry Pi. The community advises opting for a power supply that can supply at least 1A if using USB peripherals or Pi plates that draw more than a few tens of milliamps of current.

*As the 5V rail is brought out in the [[Rpi_Low-level_peripherals | GPIO pins]], you can power the Rpi from there too. You should mind however, that those are ''behind'' the power protection circuitry , so you should provide your own.
* It is possible to power the Rpi from a powered USB hub the Rpi controls, but only on 'dumb' devices, that allow the port to supply the full current without waiting for the usb device to ask for it[http://www.raspberrypi.org/forum/general-discussion/power-pi-from-usb-hub-connected-to-pi]. As the power input of the Rpi doesn't have its data leads connected, there is no chance for a communication loop of some sorts.
* POE ([http://nl.wikipedia.org/wiki/Power_over_Ethernet power over ethernet]) is currently not available for the Rpi (but nobody stops you from taking your soldering iron and doing it yourself)

===Power Supply Problems===

There have been a number of problems reported that seem to be caused by inadequate power, this is an attempt to explain what is needed and the consequences of not having enough power.

The power required by the Pi will vary depending on how busy it is and what peripherals are connected.
* Running a GUI will take more power.
* The USB devices and Ethernet connection will take power.
* Running software will take power.

This means that it's difficult to say exactly how much power is needed. People have reported current requirements of between 300mA and 550mA. But it could in reality take more, especially for short periods. A simple multimeter will not show short surges on the power requirement. A surge in the power requirement for a few milliseconds will not be detectable by a meter but will be enough to cause problems.
If the board does not get enough power the voltage will drop. If it drops enough parts of the system will run unreliably because data can get corrupted. The USB IC runs on 5V and handles the USB and Ethernet ports so it's likely that this will be the first thing to fail. Problems seen are unreliable Ethernet connection and unreliable operation of the Keyboard and/or mouse. Each USB port on the Pi has a fuse rated at 140 mA, so any connected USB devices should draw less than this amount of current. Some USB WiFi dongles are known to draw more than 150 mA when configured and active.

There are several reasons why the power to the board may be inadequate:
* The PSU may not deliver enough power. Although the maximum power requirement is said to be 700mA, that is with no peripherals connected (USB, Ethernet etc), so a 1000mA PSU should be regarded as a minimum. This allows some leeway in case the power supply cannot deliver it's full power without the voltage dropping.
* The PSU is not regulated.
* The cable connecting the PSU to the Pi may not be good. People have reported cables with 4 ohms resistance on the power connections. At 500mA drain this would reduce a 5V supply to 3V.

==Power==

The board takes fixed 5V input, (with the 1V2 core voltage generated directly from the input using the internal switch-mode supply on the BCM2835 die).
This permits adoption of the micro USB form factor, which, in turn, prevents the user from inadvertently plugging in out-of-range power inputs; that would be dangerous, since the 5V would go straight to HDMI and output USB ports, even though the problem should be mitigated by some protections applied to the input power: The board provides a polarity protection diode, a voltage clamp, and a self-resetting semiconductor fuse.

Premier Farnell recommend the following power supplies:
* Model A: 5V dc, 500-700mA
* Model B: 5V dc, 700-1200mA

Power consumption of the Raspberry Pi device is

* Board A: 5V, 500 mA (2.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI)
* Board B: 5V, 700 mA (3.5W) '''without any devices connected''' (e.g. USB, Ethernet, HDMI) (Is this correct? These [http://www.raspberrypi.org/forum/troubleshooting/usb-hub-sending-power-to-raspberry-pi-through-usb-port/#p68382] links [http://www.raspberrypi.org/forum/general-discussion/raspberry-pi-power-requirements/page-2/#p68224] suggest that the 700mA is only required if "using networking and high-current USB peripherals" [http://www.raspberrypi.org/archives/260].)

You will need to provide a power supply that can provide enough current to power the device plus any connected peripherals, and taking into account inefficiencies of the supply itself and the cable between the power supply and Raspberry Pi. The community advises opting for a power supply that can supply at least 1A if using USB peripherals or Pi plates that draw more than a few tens of milliamps of current.

*As the 5V rail is brought out in the [[Rpi_Low-level_peripherals | GPIO pins]], you can power the Rpi from there too. You should mind however, that those are ''behind'' the power protection circuitry , so you should provide your own.
* It is possible to power the Rpi from a powered USB hub the Rpi controls, but only on 'dumb' devices, that allow the port to supply the full current without waiting for the usb device to ask for it[http://www.raspberrypi.org/forum/general-discussion/power-pi-from-usb-hub-connected-to-pi]. As the power input of the Rpi doesn't have its data leads connected, there is no chance for a communication loop of some sorts.
* POE ([http://nl.wikipedia.org/wiki/Power_over_Ethernet power over ethernet]) is currently not available for the Rpi (but nobody stops you from taking your soldering iron and doing it yourself)

===Power Supply Problems===

There have been a number of problems reported that seem to be caused by inadequate power, this is an attempt to explain what is needed and the consequences of not having enough power.

The power required by the Pi will vary depending on how busy it is and what peripherals are connected.
* Running a GUI will take more power.
* The USB devices and Ethernet connection will take power.
* Running software will take power.

This means that it's difficult to say exactly how much power is needed. People have reported current requirements of between 300mA and 550mA. But it could in reality take more, especially for short periods. A simple multimeter will not show short surges on the power requirement. A surge in the power requirement for a few milliseconds will not be detectable by a meter but will be enough to cause problems.
If the board does not get enough power the voltage will drop. If it drops enough parts of the system will run unreliably because data can get corrupted. The USB IC runs on 5V and handles the USB and Ethernet ports so it's likely that this will be the first thing to fail. Problems seen are unreliable Ethernet connection and unreliable operation of the Keyboard and/or mouse. Each USB port on the Pi has a fuse rated at 140 mA, so any connected USB devices should draw less than this amount of current. Some USB WiFi dongles are known to draw more than 150 mA when configured and active.

There are several reasons why the power to the board may be inadequate:
* The PSU may not deliver enough power. Although the maximum power requirement is said to be 700mA, that is with no peripherals connected (USB, Ethernet etc), so a 1000mA PSU should be regarded as a minimum. This allows some leeway in case the power supply cannot deliver it's full power without the voltage dropping.
* The PSU is not regulated.
* The cable connecting the PSU to the Pi may not be good. People have reported cables with 4 ohms resistance on the power connections. At 500mA drain this would reduce a 5V supply to 3V.

====How Can I tell if the power supply is inadequate?====

Common symptoms of an inadequate power supply are
* Unreliable Ethernet or keyboard operation, especially if it's OK at first but not when the GUI is started.
* SD card errors at start up seems to be another symptom of poor power.

If you think you have a problem with your power supply, it is a good idea to check the actual voltage
on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board
to facilitate voltage measurements.

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have a problem with your power supply or your power cable. Anything inside, but close to the limits, of this range ''may'' indicate a problem.

[[File:RPI_Test_Points.JPG|400px]] [[File:Voltmeter.JPG|250px]]

====Things that can cause problems====
* A USB connection on a TV or PC. The USB power supply specification is for up to 500mA and if the TV implements this then it can cause problems. The system may work initially but be unreliable because as it becomes more active the power requirement increases.
* A single supply from a powered hub. Most hubs seem to deliver more than the specified current but there's no guarantee. Check the power supply rating, it must be enough to supply everything that's connected to the hub.
* A power supply that is rated for less than 700mA may work some of the time.
* Adding a USB hard disk drive. A HDD will take quite a lot of power as it starts, maybe an amp or more. It the power supply for this also supplies the Pi then this could overload things and cause trouble.
* Some complex keyboards have been reported to take a considerable amount of power, maybe up to 500mA. The Pi cannot deliver this amount of power. Simpler budget keyboards may be better. If the system works with no keyboard attached but not with a keyboard then it's worth trying a different, simpler, keyboard.

====Summary====

* If you are having unreliable operation the first thing to do is check your power supply.
* Start with a good quality regulated power supply that is rated to provide 5V and at least 1A (1000mA).
* Use a good quality micro USB cable. Cables are notorious for giving trouble so be prepared to swap for another one.
* Not all power supplies will deliver what they claim.

===Capacitor C6===
Behind the microUSB power connector is a metallic grey component called a capacitor, marked as C6 on the board. This capacitor helps stabilise the DC power on the board, but for some it has also become a place for their thumb when removing the RPI's power lead; unfortunately, this can result in the capacitor breaking off the board. It has been stated in the forums that the type of capacitor used for C6 will be changed on later RPi models for one with sturdier leads. If you do break off your C6 capacitor, it's highly likely that your RPi will still work properly, unless you have a particularly unstable power supply, but the general advice is to not use C6 as a leverage point when removing the power connector and also take care when storing or transporting your RPi if it's not fitted in a case - try not to stow the board where C6 could be knocked by other items - for example in a laptop carry case or in amongst some books.

It's unlikely that replacing a broken off C6 capacitor will be covered under warranty, but fortunately they are easy to replace if you have average soldering skills, but remember that reworking your RPi will void its warranty too. C6 is a surface mount electrolytic capacitor, rated at 200uF 16V. A replacement capacitor can be purchased from numerous sources - for example:

{{Template:RPi_Startup}}

=Typical Hardware You Will Need=
While the RPi can be used without any additional hardware (except perhaps a power supply of some kind), it won't be much use as a general computer. As with any normal PC, it is likely you will need some additional hardware.

The following are more or less essential:

* [[RPi Buying Guide|Raspberry Pi board]]
* [[#Prepared Operating System SD Card|Prepared Operating System SD Card]]
* [[#Keyboard & Mouse|USB keyboard]]
* [[#Display|Display]] (with HDMI, DVI, Composite or SCART input)
* [[#Power Supply|Power Supply]]
* [[#Cables|Cables]]

Highly suggested extras include:

* [[#Keyboard & Mouse|USB mouse]]
* [[#Additional Peripherals|Internet connectivity]] - a USB WiFi adaptor (Model A/B) or a LAN cable (Model B)
* [[#Additional Peripherals|Powered USB Hub]]
* [[#Additional Peripherals|Case]]
* [[#Additional Peripherals|SD card reader]] - if you need to prepare your own SD card

==Prepared Operating System SD Card==
As the RPi has no internal storage or built-in [[RPi Distributions|operating system]] it requires an SD-Card that is set up to boot the RPi.

* Have a look at [[RPi Easy SD Card Setup]] to create your own preloaded SD Card.
* If you want an extensive technical explanation , look here : ''Create your own preloaded card using any [[RPi VerifiedPeripherals|suitable SD]] card you have and this [[RPi Beginners#SD_card_setup| HowTo]] . ''
* Preloaded SD cards will be available from the [http://www.raspberrypi.com RPi Shop].

NOTE: An RPi SD card can only be used to boot an RPi. A normal PC will refuse to boot from an RPi SD card.

This guide will assume you have a preloaded SD card.

''To check your SD card is compatible with Linux, see [[RPi VerifiedPeripherals]].''

==Keyboard & Mouse==
Most standard USB keyboards and mice will work with the RPi. Wireless keyboard/mice should also function, and only require a single USB port for an RF dongle. In order to use a Bluetooth keyboard or mouse you would need to use a Bluetooth dongle, which again uses a single port.

Remember that the Model A has a single USB port and the Model B only has two (typically a keyboard and mouse will use a USB port each) - see [[RPi_Hardware_Basic_Setup#USB-Hub | USB Hub]] below.

''To check your mouse and keyboard are compatible with Linux, see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

==Display==
There are two main connection options for the RPi display, ''HDMI'' (high definition) and ''Composite'' (low definition).

* HD TVs and most LCD Monitors can be connected using a full-size 'male' HDMI cable, and with an inexpensive adaptor if DVI is used. HDMI versions 1.3 and 1.4 are supported, and a version 1.4 cable is recommended. The RPi outputs audio and video via HMDI, but does not support HDMI input.

* Most older TVs can be connected using Composite (a yellow-to-yellow cable). PAL and NTSC TVs are supported. When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and can be sent to your TV, to headphones, or to an amplifier. To send audio your TV, you will need a cable which adapts from 3.5mm to double (red and white) RCA connectors.

'''Note: There is no VGA output available, so older VGA monitors will require an expensive adaptor.'''

Using an HDMI to DVI-D (digital) adaptor plus a DVI to VGA adaptor will not work. HDMI does not supply the DVI-A (analogue) needed to convert to VGA - converting an HDMI or DVI-D source to VGA (or component) needs an active converter. (It can work out cheaper to buy a new monitor.) The lack of VGA has been acknowledged as a priority issue. In a [http://interviews.slashdot.org/story/11/09/14/1554243/Eben-Upton-Answers-Your-Questions Q/A with Slashdot] Eben said that they plan to look into providing some form of add-on.

''For detailed information see [[Rpi Screens]].''

==Power Supply==
The unit uses a Micro USB connection to power itself (only the power pins are connected - so it will not transfer data over this connection). A standard modern phone charger with a micro-USB connector will do, but needs to produce at least 700mA at 5 volts. Check your power supply's ratings carefully, and [http://www.raspberrypi.org/forum/general-discussion/power-supply-warning beware cheap knock-offs!]. Suitable mains adaptors will be available from the [http://www.raspberrypi.com RPi Shop] and are recommended if you are unsure what to use.

You can use a range of other power sources (assuming they are able to provide enough current ~700mA):
* Computer USB Port or powered USB hub (will depend on power output)
* Special wall warts with USB ports
* Mobile Phone Backup Battery (will depend on power output) (in theory - needs confirmation)

To use the above, you'll need a USB A 'male' to USB micro 'male' cable - these are often shipped as data cables with mobile phones.

''For detailed information about power requirements see [[Rpi_Hardware#Power | RPi Hardware - Power]].''

==Cables==
You will probably need a number of cables in order to connect your RPi up.
# Micro-B USB Power Cable (see above) [http://en.wikipedia.org/wiki/File:MicroB_USB_Plug.jpg picture]. This has to be a [[On the RPi usb power cable|high quality one]].
# HDMI-A [http://en.wikipedia.org/wiki/File:HDMI.jpg picture] or Composite cable [http://en.wikipedia.org/wiki/File:Composite-video-cable.jpg picture], plus DVI adaptor [http://en.wikipedia.org/wiki/File:Adapter_dvi_hdmi_S7302224_wp.jpg picture] or SCART adaptor [http://en.wikipedia.org/wiki/File:Multiconnector-scart-chti.jpg picture] if required, to connect your RPi to the Display/Monitor/TV of your choice.
# Audio cable [http://en.wikipedia.org/wiki/File:Audio-TRS-Mini-Plug.jpg picture], this is not needed if you use a HDMI TV/monitor.
# Ethernet/LAN Cable (see below) [http://en.wikipedia.org/wiki/File:Ethernet_RJ45_connector_p1160054.jpg picture].

The price you pay for an HDMI cable can very wildly and under most circumstances a low-cost cable from a reputable online or local supplier will be absolutely fine, but the definition of what constitutes 'low cost' can vary wildly - for example, in the UK, a 1m cable can be purchased for anything between £1 and £24.99.
If, however, you want to drive a display some distance from the RPi (say greater than the ubiquitous 1.8m/6ft), or you are using a video switch to share a display between several devices, then higher quality cables might be wise - for example, a pair of 1m HDMI cables purchased in a UK 'pound shop' worked fine when directly connected between the RPi and a display, but would not give a stable picture when used via an HDMI switch. Replacing the £1 1m cable with a 1.5m cable bought online for £1.30 fixed the problem.
For more insight: [http://www.techradar.com/news/video/why-you-dont-need-to-spend-more-than-2-on-an-hdmi-cable-1071343 Why you don't need to spend more than £2 on an HDMI cable]

==Additional Peripherals==
You may decide you want to use various other devices with your RPi, such as Flash Drives/Portable Hard Drives, Speakers etc.

''For detailed information see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===Internet Connectivity===

This may be an Ethernet/LAN cable (standard RJ45 connector) or a USB WiFi adaptor. The RPi ethernet port is auto-sensing which means that it may be connected to a router or directly to another computer (without the need for a crossover cable<ref name=autoMDIX>[http://en.wikipedia.org/wiki/Medium_dependent_interface#Auto-MDIX Wikipedia:Auto-MDIX]</ref>).

''Support for USB WiFi adaptors will vary - see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===USB-Hub===
In order to connect additional devices to the RPi, you may want to obtain a USB Hub, which will allow multiple devices to be used.

It is recommended that a '''powered''' hub is used - this will provide any additional power to the devices without affecting the RPi itself (see [[Rpi_Hardware#Power | RPi Hardware - Power]] section).

USB version 2.0 is recommended. USB version 1.1 is fine for keyboards and mice, but may not be fast enough for other accessories.

===Case===
Since the RPi is supplied without a case, it will be important to ensure that you do not use it in places where it will come into contact with conductive metal or liquids, unless suitably protected. Some form of [[Rpi Cases | case]] should be considered, and there is a [http://www.raspberrypi.org/forum/general-discussion/cases-for-the-raspberry-pi Rpi case thread] on the forum.

''For detailed information see [[Rpi Cases]].''

===SD card reader===
If you will not use a preloaded SD card to boot from, you will need an SD card reader to prepare an SD card.

Note that the SD card reader will be connected to a traditional PC, not to the RPi. You may use an SD card reader integrated into your PC, or you may use a dedicated USB-connected SD card reader. Note that several peripherals may also be used as an SD card reader, for example cameras, smartphones, camcorders and GPS units.

===Expansion & Low Level Peripherals===
If you plan on making use of the low level interfaces available on the RPi, then ensure you have suitable header pins for the GPIO (and if required JTAG) suitable for your needs.

Also if you have a particular low-level project in mind, then ensure you design in suitable protection circuits to keep your RPi safe (details will be made available within the [[RaspberryPiBoardProjects | RPi Projects, Guides & Tutorials]] section).

''For detailed information see [[Rpi Low-level peripherals | Rpi Low-level Peripherals]].''

=Connecting Together=

[[File:Raspi-Model-AB-Mono-1-699x1024.png|200px|thumb|right|A diagram denoting the places of the different components on the Rpi, made by Paul Beech. Click to enlarge.]]
You can use the diagram to connect everything together, or use the following instructions:

# Plug the preloaded SD Card into the Pi.
# Plug the USB keyboard and mouse into the Pi, perhaps via a USB Hub. Connect the Hub to power, if necessary.

RPi Hardware Basic Setup

2012-05-08T19:39:40Z

Linker3000: /* Cables */

[[Category:RaspberryPi]]
{{Template:RPi_Startup}}

=Typical Hardware You Will Need=
While the RPi can be used without any additional hardware (except perhaps a power supply of some kind), it won't be much use as a general computer. As with any normal PC, it is likely you will need some additional hardware.

The following are more or less essential:

* [[RPi Buying Guide|Raspberry Pi board]]
* [[#Prepared Operating System SD Card|Prepared Operating System SD Card]]
* [[#Keyboard & Mouse|USB keyboard]]
* [[#Display|Display]] (with HDMI, DVI, Composite or SCART input)
* [[#Power Supply|Power Supply]]
* [[#Cables|Cables]]

Highly suggested extras include:

* [[#Keyboard & Mouse|USB mouse]]
* [[#Additional Peripherals|Internet connectivity]] - a USB WiFi adaptor (Model A/B) or a LAN cable (Model B)
* [[#Additional Peripherals|Powered USB Hub]]
* [[#Additional Peripherals|Case]]
* [[#Additional Peripherals|SD card reader]] - if you need to prepare your own SD card

==Prepared Operating System SD Card==
As the RPi has no internal storage or built-in [[RPi Distributions|operating system]] it requires an SD-Card that is set up to boot the RPi.

* Have a look at [[RPi Easy SD Card Setup]] to create your own preloaded SD Card.
* If you want an extensive technical explanation , look here : ''Create your own preloaded card using any [[RPi VerifiedPeripherals|suitable SD]] card you have and this [[RPi Beginners#SD_card_setup| HowTo]] . ''
* Preloaded SD cards will be available from the [http://www.raspberrypi.com RPi Shop].

NOTE: An RPi SD card can only be used to boot an RPi. A normal PC will refuse to boot from an RPi SD card.

This guide will assume you have a preloaded SD card.

''To check your SD card is compatible with Linux, see [[RPi VerifiedPeripherals]].''

==Keyboard & Mouse==
Most standard USB keyboards and mice will work with the RPi. Wireless keyboard/mice should also function, and only require a single USB port for an RF dongle. In order to use a Bluetooth keyboard or mouse you would need to use a Bluetooth dongle, which again uses a single port.

Remember that the Model A has a single USB port and the Model B only has two (typically a keyboard and mouse will use a USB port each) - see [[RPi_Hardware_Basic_Setup#USB-Hub | USB Hub]] below.

''To check your mouse and keyboard are compatible with Linux, see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

==Display==
There are two main connection options for the RPi display, ''HDMI'' (high definition) and ''Composite'' (low definition).

* HD TVs and most LCD Monitors can be connected using a full-size 'male' HDMI cable, and with an inexpensive adaptor if DVI is used. HDMI versions 1.3 and 1.4 are supported, and a version 1.4 cable is recommended. The RPi outputs audio and video via HMDI, but does not support HDMI input.

* Most older TVs can be connected using Composite (a yellow-to-yellow cable). PAL and NTSC TVs are supported. When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and can be sent to your TV, to headphones, or to an amplifier. To send audio your TV, you will need a cable which adapts from 3.5mm to double (red and white) RCA connectors.

'''Note: There is no VGA output available, so older VGA monitors will require an expensive adaptor.'''

Using an HDMI to DVI-D (digital) adaptor plus a DVI to VGA adaptor will not work. HDMI does not supply the DVI-A (analogue) needed to convert to VGA - converting an HDMI or DVI-D source to VGA (or component) needs an active converter. (It can work out cheaper to buy a new monitor.) The lack of VGA has been acknowledged as a priority issue. In a [http://interviews.slashdot.org/story/11/09/14/1554243/Eben-Upton-Answers-Your-Questions Q/A with Slashdot] Eben said that they plan to look into providing some form of add-on.

''For detailed information see [[Rpi Screens]].''

==Power Supply==
The unit uses a Micro USB connection to power itself (only the power pins are connected - so it will not transfer data over this connection). A standard modern phone charger with a micro-USB connector will do, but needs to produce at least 700mA at 5 volts. Check your power supply's ratings carefully, and [http://www.raspberrypi.org/forum/general-discussion/power-supply-warning beware cheap knock-offs!]. Suitable mains adaptors will be available from the [http://www.raspberrypi.com RPi Shop] and are recommended if you are unsure what to use.

You can use a range of other power sources (assuming they are able to provide enough current ~700mA):
* Computer USB Port or powered USB hub (will depend on power output)
* Special wall warts with USB ports
* Mobile Phone Backup Battery (will depend on power output) (in theory - needs confirmation)

To use the above, you'll need a USB A 'male' to USB micro 'male' cable - these are often shipped as data cables with mobile phones.

''For detailed information about power requirements see [[Rpi_Hardware#Power | RPi Hardware - Power]].''

==Cables==
You will probably need a number of cables in order to connect your RPi up.
# Micro-B USB Power Cable (see above) [http://en.wikipedia.org/wiki/File:MicroB_USB_Plug.jpg picture]. This has to be a [[On the RPi usb power cable|high quality one]].
# HDMI-A [http://en.wikipedia.org/wiki/File:HDMI.jpg picture] or Composite cable [http://en.wikipedia.org/wiki/File:Composite-video-cable.jpg picture], plus DVI adaptor [http://en.wikipedia.org/wiki/File:Adapter_dvi_hdmi_S7302224_wp.jpg picture] or SCART adaptor [http://en.wikipedia.org/wiki/File:Multiconnector-scart-chti.jpg picture] if required, to connect your RPi to the Display/Monitor/TV of your choice.
# Audio cable [http://en.wikipedia.org/wiki/File:Audio-TRS-Mini-Plug.jpg picture], this is not needed if you use a HDMI TV/monitor.
# Ethernet/LAN Cable (see below) [http://en.wikipedia.org/wiki/File:Ethernet_RJ45_connector_p1160054.jpg picture].

The price you pay for an HDMI cable can very wildly and under most circumstances a low-cost cable from a reputable online or local supplier will be absolutely fine, but the definition of what constitutes 'low cost' can vary wildly - for example, in the UK, a 1m cable can be purchased for anything between £1 and £24.99.
If, however, you want to drive a display some distance from the RPi (say greater than the ubiquitous 1.8m/6ft), or you are using a video switch to share a display bewteen several devices, then higher quality cables might be wise - for example, a pair of 1m HDMI cables purchased in a UK 'pound shop' worked fine when directly connected between the RPi and a display, but would not give a stable picture when used via an HDMI switch. Replacing the £1 1m cable with a 1.5m cable bought online for £1.30 fixed the problem.
For more insight: [http://www.techradar.com/news/video/why-you-dont-need-to-spend-more-than-2-on-an-hdmi-cable-1071343 Why you don't need to spend more than £2 on an HDMI cable]

==Additional Peripherals==
You may decide you want to use various other devices with your RPi, such as Flash Drives/Portable Hard Drives, Speakers etc.

''For detailed information see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===Internet Connectivity===

This may be an Ethernet/LAN cable (standard RJ45 connector) or a USB WiFi adaptor. The RPi ethernet port is auto-sensing which means that it may be connected to a router or directly to another computer (without the need for a crossover cable<ref name=autoMDIX>[http://en.wikipedia.org/wiki/Medium_dependent_interface#Auto-MDIX Wikipedia:Auto-MDIX]</ref>).

''Support for USB WiFi adaptors will vary - see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===USB-Hub===
In order to connect additional devices to the RPi, you may want to obtain a USB Hub, which will allow multiple devices to be used.

It is recommended that a '''powered''' hub is used - this will provide any additional power to the devices without affecting the RPi itself (see [[Rpi_Hardware#Power | RPi Hardware - Power]] section).

USB version 2.0 is recommended. USB version 1.1 is fine for keyboards and mice, but may not be fast enough for other accessories.

===Case===
Since the RPi is supplied without a case, it will be important to ensure that you do not use it in places where it will come into contact with conductive metal or liquids, unless suitably protected. Some form of [[Rpi Cases | case]] should be considered, and there is a [http://www.raspberrypi.org/forum/general-discussion/cases-for-the-raspberry-pi Rpi case thread] on the forum.

''For detailed information see [[Rpi Cases]].''

===SD card reader===
If you will not use a preloaded SD card to boot from, you will need an SD card reader to prepare an SD card.

Note that the SD card reader will be connected to a traditional PC, not to the RPi. You may use an SD card reader integrated into your PC, or you may use a dedicated USB-connected SD card reader. Note that several peripherals may also be used as an SD card reader, for example cameras, smartphones, camcorders and GPS units.

===Expansion & Low Level Peripherals===
If you plan on making use of the low level interfaces available on the RPi, then ensure you have suitable header pins for the GPIO (and if required JTAG) suitable for your needs.

Also if you have a particular low-level project in mind, then ensure you design in suitable protection circuits to keep your RPi safe (details will be made available within the [[RaspberryPiBoardProjects | RPi Projects, Guides & Tutorials]] section).

''For detailed information see [[Rpi Low-level peripherals | Rpi Low-level Peripherals]].''

=Connecting Together=

[[File:Raspi-Model-AB-Mono-1-699x1024.png|200px|thumb|right|A diagram denoting the places of the different components on the Rpi, made by Paul Beech. Click to enlarge.]]
You can use the diagram to connect everything together, or use the following instructions:

# Plug the preloaded SD Card into the Pi.
# Plug the USB keyboard and mouse into the Pi, perhaps via a USB Hub. Connect the Hub to power, if necessary.
# Plug the video cable into the screen (TV) and into the Pi.
# Plug your extras into the Pi (USB WiFi, Ethernet cable, hard drive etc.). This is where you may really need a USB Hub.
# Ensure that your USB Hub (if any) and screen are working.
# Plug the power source into the main socket.
# With your screen on, plug the other end of the power source into the Pi.
# The Pi should boot up and display messages on the screen.

It is always recommended to connect the MicroUSB Power to the unit last (while most connections can be made live, it is best practice to connect items such as displays and other connections with the power turned off).

The RPi may take a long time to boot when powered-on for the first time, so be patient!

RPi Hardware Basic Setup

2012-04-29T08:57:45Z

Linker3000: /* Cables */

[[Category:RaspberryPi]]
{{Template:RPi_Startup}}

=Typical Hardware You Will Need=
While the RPi can be used without any additional hardware (except perhaps a power supply of some kind), it won't be much use as a general computer. As with any normal PC, it is likely you will need some additional hardware.

The following are more or less essential:

* [[RPi Buying Guide|Raspberry Pi board]]
* [[#Prepared Operating System SD Card|Prepared Operating System SD Card]]
* [[#Keyboard & Mouse|USB keyboard]]
* [[#Display|Display]] (with HDMI, DVI, Composite or SCART input)
* [[#Power Supply|Power Supply]]
* [[#Cables|Cables]]

Highly suggested extras include:

* [[#Keyboard & Mouse|USB mouse]]
* [[#Additional Peripherals|Internet connectivity]] - a USB WiFi adaptor (Model A/B) or a LAN cable (Model B)
* [[#Additional Peripherals|Powered USB Hub]]
* [[#Additional Peripherals|Case]]
* [[#Additional Peripherals|SD card reader]] - if you need to prepare your own SD card

==Prepared Operating System SD Card==
As the RPi has no internal storage or built-in [[RPi Distributions|operating system]] it requires an SD-Card that is set up to boot the RPi.

* Have a look at [[RPi Easy SD Card Setup]] to create your own preloaded SD Card.
* If you want an extensive technical explanation , look here : ''Create your own preloaded card using any [[RPi VerifiedPeripherals|suitable SD]] card you have and this [[RPi Beginners#SD_card_setup| HowTo]] . ''
* Preloaded SD cards will be available from the [http://www.raspberrypi.com RPi Shop].

NOTE: An RPi SD card can only be used to boot an RPi. A normal PC will refuse to boot from an RPi SD card.

This guide will assume you have a preloaded SD card.

''To check your SD card is compatible with Linux, see [[RPi VerifiedPeripherals]].''

==Keyboard & Mouse==
Most standard USB keyboards and mice will work with the RPi. Wireless keyboard/mice should also function, and only require a single USB port for an RF dongle. In order to use a Bluetooth keyboard or mouse you would need to use a Bluetooth dongle, which again uses a single port.

Remember that the Model A has a single USB port and the Model B only has two (typically a keyboard and mouse will use a USB port each) - see [[RPi_Hardware_Basic_Setup#USB-Hub | USB Hub]] below.

''To check your mouse and keyboard are compatible with Linux, see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

==Display==
There are two main connection options for the RPi display, ''HDMI'' (high definition) and ''Composite'' (low definition).

* HD TVs and most LCD Monitors can be connected using a full-size 'male' HDMI cable, and with an inexpensive adaptor if DVI is used. HDMI versions 1.3 and 1.4 are supported, and a version 1.4 cable is recommended. The RPi outputs audio and video via HMDI, but does not support HDMI input.

* Most older TVs can be connected using Composite (a yellow-to-yellow cable). PAL and NTSC TVs are supported. When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and can be sent to your TV, to headphones, or to an amplifier. To send audio your TV, you will need a cable which adapts from 3.5mm to double (red and white) RCA connectors.

'''Note: There is no VGA output available, so older VGA monitors will require an expensive adaptor.'''

Using an HDMI to DVI-D (digital) adaptor plus a DVI to VGA adaptor will not work. HDMI does not supply the DVI-A (analogue) needed to convert to VGA - converting an HDMI or DVI-D source to VGA (or component) needs an active converter. (It can work out cheaper to buy a new monitor.) The lack of VGA has been acknowledged as a priority issue. In a [http://interviews.slashdot.org/story/11/09/14/1554243/Eben-Upton-Answers-Your-Questions Q/A with Slashdot] Eben said that they plan to look into providing some form of add-on.

''For detailed information see [[Rpi Screens]].''

==Power Supply==
The unit uses a Micro USB connection to power itself (only the power pins are connected - so it will not transfer data over this connection). A standard modern phone charger with a micro-USB connector will do, but needs to produce at least 700mA at 5 volts. Check your power supply's ratings carefully, and [http://www.raspberrypi.org/forum/general-discussion/power-supply-warning beware cheap knock-offs!]. Suitable mains adaptors will be available from the [http://www.raspberrypi.com RPi Shop] and are recommended if you are unsure what to use.

You can use a range of other power sources (assuming they are able to provide enough current ~700mA):
* Computer USB Port or powered USB hub (will depend on power output)
* Special wall warts with USB ports
* Mobile Phone Backup Battery (will depend on power output) (in theory - needs confirmation)

To use the above, you'll need a USB A 'male' to USB micro 'male' cable - these are often shipped as data cables with mobile phones.

''For detailed information about power requirements see [[Rpi_Hardware#Power | RPi Hardware - Power]].''

==Cables==
You will probably need a number of cables in order to connect your RPi up.
# Micro-B USB Power Cable (see above) [http://en.wikipedia.org/wiki/File:MicroB_USB_Plug.jpg picture]. This has to be a [[On the RPi usb power cable|high quality one]].
# HDMI-A [http://en.wikipedia.org/wiki/File:HDMI.jpg picture] or Composite cable [http://en.wikipedia.org/wiki/File:Composite-video-cable.jpg picture], plus DVI adaptor [http://en.wikipedia.org/wiki/File:Adapter_dvi_hdmi_S7302224_wp.jpg picture] or SCART adaptor [http://en.wikipedia.org/wiki/File:Multiconnector-scart-chti.jpg picture] if required, to connect your RPi to the Display/Monitor/TV of your choice.
# Audio cable [http://en.wikipedia.org/wiki/File:Audio-TRS-Mini-Plug.jpg picture], this is not needed if you use a HDMI TV/monitor.
# Ethernet/LAN Cable (see below) [http://en.wikipedia.org/wiki/File:Ethernet_RJ45_connector_p1160054.jpg picture].

The price you pay for an HDMI cable can very wildly and under most circumstances a low-cost cable from a reputable online or local supplier will be absolutely fine, but the definition of what constitutes 'low cost' can vary wildly - for example, in the UK, a 1m cable can be purchased for anything between £1 and £24.99. This article explains things very nicely: [http://www.techradar.com/news/video/why-you-dont-need-to-spend-more-than-2-on-an-hdmi-cable-1071343 Why you don't need to spend more than £2 on an HDMI cable]

==Additional Peripherals==
You may decide you want to use various other devices with your RPi, such as Flash Drives/Portable Hard Drives, Speakers etc.

''For detailed information see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===Internet Connectivity===

This may be an Ethernet/LAN cable (standard RJ45 connector) or a USB WiFi adaptor. The RPi ethernet port is auto-sensing which means that it may be connected to a router or directly to another computer (without the need for a crossover cable<ref name=autoMDIX>[http://en.wikipedia.org/wiki/Medium_dependent_interface#Auto-MDIX Wikipedia:Auto-MDIX]</ref>).

''Support for USB WiFi adaptors will vary - see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===USB-Hub===
In order to connect additional devices to the RPi, you may want to obtain a USB Hub, which will allow multiple devices to be used.

It is recommended that a '''powered''' hub is used - this will provide any additional power to the devices without affecting the RPi itself (see [[Rpi_Hardware#Power | RPi Hardware - Power]] section).

USB version 2.0 is recommended. USB version 1.1 is fine for keyboards and mice, but may not be fast enough for other accessories.

===Case===
Since the RPi is supplied without a case, it will be important to ensure that you do not use it in places where it will come into contact with conductive metal or liquids, unless suitably protected. Some form of [[Rpi Cases | case]] should be considered, and there is a [http://www.raspberrypi.org/forum/general-discussion/cases-for-the-raspberry-pi Rpi case thread] on the forum.

''For detailed information see [[Rpi Cases]].''

===SD card reader===
If you will not use a preloaded SD card to boot from, you will need an SD card reader to prepare an SD card.

Note that the SD card reader will be connected to a traditional PC, not to the RPi. You may use an SD card reader integrated into your PC, or you may use a dedicated USB-connected SD card reader. Note that several peripherals may also be used as an SD card reader, for example cameras, smartphones, camcorders and GPS units.

===Expansion & Low Level Peripherals===
If you plan on making use of the low level interfaces available on the RPi, then ensure you have suitable header pins for the GPIO (and if required JTAG) suitable for your needs.

Also if you have a particular low-level project in mind, then ensure you design in suitable protection circuits to keep your RPi safe (details will be made available within the [[RaspberryPiBoardProjects | RPi Projects, Guides & Tutorials]] section).

''For detailed information see [[Rpi Low-level peripherals | Rpi Low-level Peripherals]].''

=Connecting Together=

[[File:Raspi-Model-AB-Mono-1-699x1024.png|200px|thumb|right|A diagram denoting the places of the different components on the Rpi, made by Paul Beech. Click to enlarge.]]
You can use the diagram to connect everything together, or use the following instructions:

# Plug the preloaded SD Card into the Pi.
# Plug the USB keyboard and mouse into the Pi, perhaps via a USB Hub. Connect the Hub to power, if necessary.
# Plug the video cable into the screen (TV) and into the Pi.
# Plug your extras into the Pi (USB WiFi, Ethernet cable, hard drive etc.). This is where you may really need a USB Hub.
# Ensure that your USB Hub (if any) and screen are working.
# Plug the power source into the main socket.
# With your screen on, plug the other end of the power source into the Pi.
# The Pi should boot up and display messages on the screen.

It is always recommended to connect the MicroUSB Power to the unit last (while most connections can be made live, it is best practice to connect items such as displays and other connections with the power turned off).

The RPi may take a long time to boot when powered-on for the first time, so be patient!

RPi Hardware Basic Setup

2012-04-28T16:51:54Z

Linker3000: /* Cables */

[[Category:RaspberryPi]]
{{Template:RPi_Startup}}

=Typical Hardware You Will Need=
While the RPi can be used without any additional hardware (except perhaps a power supply of some kind), it won't be much use as a general computer. As with any normal PC, it is likely you will need some additional hardware.

The following are more or less essential:

* [[RPi Buying Guide|Raspberry Pi board]]
* [[#Prepared Operating System SD Card|Prepared Operating System SD Card]]
* [[#Keyboard & Mouse|USB keyboard]]
* [[#Display|Display]] (with HDMI, DVI, Composite or SCART input)
* [[#Power Supply|Power Supply]]
* [[#Cables|Cables]]

Highly suggested extras include:

* [[#Keyboard & Mouse|USB mouse]]
* [[#Additional Peripherals|Internet connectivity]] - a USB WiFi adaptor (Model A/B) or a LAN cable (Model B)
* [[#Additional Peripherals|Powered USB Hub]]
* [[#Additional Peripherals|Case]]
* [[#Additional Peripherals|SD card reader]] - if you need to prepare your own SD card

==Prepared Operating System SD Card==
As the RPi has no internal storage or built-in [[RPi Distributions|operating system]] it requires an SD-Card that is set up to boot the RPi.

* Have a look at [[RPi Easy SD Card Setup]] to create your own preloaded SD Card.
* If you want an extensive technical explanation , look here : ''Create your own preloaded card using any [[RPi VerifiedPeripherals|suitable SD]] card you have and this [[RPi Beginners#SD_card_setup| HowTo]] . ''
* Preloaded SD cards will be available from the [http://www.raspberrypi.com RPi Shop].

NOTE: An RPi SD card can only be used to boot an RPi. A normal PC will refuse to boot from an RPi SD card.

This guide will assume you have a preloaded SD card.

''To check your SD card is compatible with Linux, see [[RPi VerifiedPeripherals]].''

==Keyboard & Mouse==
Most standard USB keyboards and mice will work with the RPi. Wireless keyboard/mice should also function, and only require a single USB port for an RF dongle. In order to use a Bluetooth keyboard or mouse you would need to use a Bluetooth dongle, which again uses a single port.

Remember that the Model A has a single USB port and the Model B only has two (typically a keyboard and mouse will use a USB port each) - see [[RPi_Hardware_Basic_Setup#USB-Hub | USB Hub]] below.

''To check your mouse and keyboard are compatible with Linux, see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

==Display==
There are two main connection options for the RPi display, ''HDMI'' (high definition) and ''Composite'' (low definition).

* HD TVs and most LCD Monitors can be connected using a full-size 'male' HDMI cable, and with an inexpensive adaptor if DVI is used. HDMI versions 1.3 and 1.4 are supported, and a version 1.4 cable is recommended. The RPi outputs audio and video via HMDI, but does not support HDMI input.

* Most older TVs can be connected using Composite (a yellow-to-yellow cable). PAL and NTSC TVs are supported. When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and can be sent to your TV, to headphones, or to an amplifier. To send audio your TV, you will need a cable which adapts from 3.5mm to double (red and white) RCA connectors.

'''Note: There is no VGA output available, so older VGA monitors will require an expensive adaptor.'''

Using an HDMI to DVI-D (digital) adaptor plus a DVI to VGA adaptor will not work. HDMI does not supply the DVI-A (analogue) needed to convert to VGA - converting an HDMI or DVI-D source to VGA (or component) needs an active converter. (It can work out cheaper to buy a new monitor.) The lack of VGA has been acknowledged as a priority issue. In a [http://interviews.slashdot.org/story/11/09/14/1554243/Eben-Upton-Answers-Your-Questions Q/A with Slashdot] Eben said that they plan to look into providing some form of add-on.

''For detailed information see [[Rpi Screens]].''

==Power Supply==
The unit uses a Micro USB connection to power itself (only the power pins are connected - so it will not transfer data over this connection). A standard modern phone charger with a micro-USB connector will do, but needs to produce at least 700mA at 5 volts. Check your power supply's ratings carefully, and [http://www.raspberrypi.org/forum/general-discussion/power-supply-warning beware cheap knock-offs!]. Suitable mains adaptors will be available from the [http://www.raspberrypi.com RPi Shop] and are recommended if you are unsure what to use.

You can use a range of other power sources (assuming they are able to provide enough current ~700mA):
* Computer USB Port or powered USB hub (will depend on power output)
* Special wall warts with USB ports
* Mobile Phone Backup Battery (will depend on power output) (in theory - needs confirmation)

To use the above, you'll need a USB A 'male' to USB micro 'male' cable - these are often shipped as data cables with mobile phones.

''For detailed information about power requirements see [[Rpi_Hardware#Power | RPi Hardware - Power]].''

==Cables==
You will probably need a number of cables in order to connect your RPi up.
# Micro-B USB Power Cable (see above) [http://en.wikipedia.org/wiki/File:MicroB_USB_Plug.jpg picture]. This has to be a [[On the RPi usb power cable|high quality one]].
# HDMI-A [http://en.wikipedia.org/wiki/File:HDMI.jpg picture] or Composite cable [http://en.wikipedia.org/wiki/File:Composite-video-cable.jpg picture], plus DVI adaptor [http://en.wikipedia.org/wiki/File:Adapter_dvi_hdmi_S7302224_wp.jpg picture] or SCART adaptor [http://en.wikipedia.org/wiki/File:Multiconnector-scart-chti.jpg picture] if required, to connect your RPi to the Display/Monitor/TV of your choice.
# Audio cable [http://en.wikipedia.org/wiki/File:Audio-TRS-Mini-Plug.jpg picture], this is not needed if you use a HDMI TV/monitor.
# Ethernet/LAN Cable (see below) [http://en.wikipedia.org/wiki/File:Ethernet_RJ45_connector_p1160054.jpg picture].

The price you pay for an HDMI cable can very wildly and under most circumstances a low-cost cable from a reputable online or local supplier will be absolutely fine, but the definition of what constitutes 'low cost' can vary wildly - for example, in the UK, a 1m cable can be purchased for anything between £1 and £24.99. This article explains things very nicely: [http://www.techradar.com/news/…..le-1071343 Why you don't need to spend more than £2 on an HDMI cable]

==Additional Peripherals==
You may decide you want to use various other devices with your RPi, such as Flash Drives/Portable Hard Drives, Speakers etc.

''For detailed information see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===Internet Connectivity===

This may be an Ethernet/LAN cable (standard RJ45 connector) or a USB WiFi adaptor. The RPi ethernet port is auto-sensing which means that it may be connected to a router or directly to another computer (without the need for a crossover cable<ref name=autoMDIX>[http://en.wikipedia.org/wiki/Medium_dependent_interface#Auto-MDIX Wikipedia:Auto-MDIX]</ref>).

''Support for USB WiFi adaptors will vary - see [[RPi VerifiedPeripherals | RPi Verified Peripherals]].''

===USB-Hub===
In order to connect additional devices to the RPi, you may want to obtain a USB Hub, which will allow multiple devices to be used.

It is recommended that a '''powered''' hub is used - this will provide any additional power to the devices without affecting the RPi itself (see [[Rpi_Hardware#Power | RPi Hardware - Power]] section).

USB version 2.0 is recommended. USB version 1.1 is fine for keyboards and mice, but may not be fast enough for other accessories.

===Case===
Since the RPi is supplied without a case, it will be important to ensure that you do not use it in places where it will come into contact with conductive metal or liquids, unless suitably protected. Some form of [[Rpi Cases | case]] should be considered, and there is a [http://www.raspberrypi.org/forum/general-discussion/cases-for-the-raspberry-pi Rpi case thread] on the forum.

''For detailed information see [[Rpi Cases]].''

===SD card reader===
If you will not use a preloaded SD card to boot from, you will need an SD card reader to prepare an SD card.

Note that the SD card reader will be connected to a traditional PC, not to the RPi. You may use an SD card reader integrated into your PC, or you may use a dedicated USB-connected SD card reader. Note that several peripherals may also be used as an SD card reader, for example cameras, smartphones, camcorders and GPS units.

===Expansion & Low Level Peripherals===
If you plan on making use of the low level interfaces available on the RPi, then ensure you have suitable header pins for the GPIO (and if required JTAG) suitable for your needs.

Also if you have a particular low-level project in mind, then ensure you design in suitable protection circuits to keep your RPi safe (details will be made available within the [[RaspberryPiBoardProjects | RPi Projects, Guides & Tutorials]] section).

''For detailed information see [[Rpi Low-level peripherals | Rpi Low-level Peripherals]].''

=Connecting Together=

[[File:Raspi-Model-AB-Mono-1-699x1024.png|200px|thumb|right|A diagram denoting the places of the different components on the Rpi, made by Paul Beech. Click to enlarge.]]
You can use the diagram to connect everything together, or use the following instructions:

# Plug the preloaded SD Card into the Pi.
# Plug the USB keyboard and mouse into the Pi, perhaps via a USB Hub. Connect the Hub to power, if necessary.
# Plug the video cable into the screen (TV) and into the Pi.
# Plug your extras into the Pi (USB WiFi, Ethernet cable, hard drive etc.). This is where you may really need a USB Hub.
# Ensure that your USB Hub (if any) and screen are working.
# Plug the power source into the main socket.
# With your screen on, plug the other end of the power source into the Pi.
# The Pi should boot up and display messages on the screen.

It is always recommended to connect the MicroUSB Power to the unit last (while most connections can be made live, it is best practice to connect items such as displays and other connections with the power turned off).

The RPi may take a long time to boot when powered-on for the first time, so be patient!

RPi Easy SD Card Setup

2012-04-28T08:41:02Z

Linker3000: /* SD Card setup */

[[Category: RaspberryPi]]
{{Template:RPi_Startup}}

=SD Card setup=
To boot the Raspberry Pi, you need an SD card installed with a bootloader and a suitable Operating System. Some Raspberry Pi kits will come with a ready-to-go card, but if you didn't receive one you will need to prepare your own:

Official images are available from http://www.raspberrypi.org/downloads and there is an overview of available distributions [[RPi_Distributions | here]].

Warning! When you write the Raspberry Pi image to your SD card you will lose all data that was on the card.

=Safest/Laziest way=
Buy a preloaded card from RS Components or element14 (not available yet)

=Easiest way=

* Download and run the PiCard tool. It will guide you through the progress. See [http://code.google.com/p/rasp-pi-card/ the google code repo] and the [http://www.raspberrypi.org/forum/projects-and-collaboration-general/picard-gui-sd-preparation-tool/page-18 forum discussion].'''The PiCard project has now been disbanded'''

* Use an installer program. The [http://zenit.senecac.on.ca/wiki/index.php/Raspberry_Pi_Fedora_Remix_Installation#SD_Card_Installation_Using_the_Installer Fedora ARM Installer] will download and install Raspberry Pi Fedora Remix images, but it will also install other images if they are already downloaded and in uncompressed or .gz format.

* ('''Mac''') The [http://exaviorn.com/raspiwrite/ RasPiWrite] utility is a python script which will walk you through the process of installing to SD card, it is works with any Raspberry Pi compatible disk image, and can download one of the currently available distros if you don't have one.

=Easy way=

To write your SD card you start by downloading the SD image (the data you will write to the card). The best way to do this is using [http://en.wikipedia.org/wiki/BitTorrent_(protocol) BitTorrent]. This generally results in a faster download as it is a highly distributed system (you will be downloading the data from users who have previously downloaded it).

This guide assumes you have downloaded the Debian "squeeze" image, with name debian6-13-04-2012. Obviously, if you are downloading a different or newer version, use the name of the version you have downloaded.

==Copying the image to an SD Card on Windows==

# Download the image from a mirror or torrent
#* http://www.raspberrypi.org/downloads
# Extract the image file debian6-13-04-2012.img from the debian6-13-04-2012 directory in the debian6-13-04-2012.zip
# Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer.
# Download the [https://launchpad.net/win32-image-writer Win32DiskImager] utility. The download links are on the right hand side of the page, you want the binary zip.
# Extract the zip file and run the Win32DiskImager utility.
# Select the debian6-13-04-2012.img image file you extracted earlier
# Select the drive letter of the SD card in the device box. Be careful to select the correct drive; if you get the wrong one you can destroy your computer's hard disk!
# Click Write and wait for the write to complete.
# Exit the imager and eject the SD card.
# Insert the card in the Raspberry Pi, power it on, and it should boot up. Have fun!
''In Windows the SD card will appear only to have a fairly small size - about 75 Mbytes. This is because most of the card has a partition that is formatted for the Linux operating system that the RPi uses and is not visible in Windows.
''

==Copying the image to an SD Card on Windows if first option isn't succesfull==
I wasn't able to choose device in Win32DiskImager on my notebook so I find different way how to achieve same thing on windows machine..

# Download the image from a mirror or torrent
#* http://www.raspberrypi.org/downloads
# Extract the image file debian6-13-04-2012.img from the debian6-13-04-2012 directory in the debian6-13-04-2012.zip
# Insert the SD card into your SD card reader and check what drive letter it was assigned. You can easily see the drive letter (for example H:) by looking in the left column of Windows Explorer.
# Download flashnul software from http://shounen.ru/soft/flashnul/ here is [http://translate.google.com/translate?u=http%3A%2F%2Fshounen.ru%2Fsoft%2Fflashnul%2F&hl=en&ie=UTF8&sl=ru&tl=en Translated version]
#* Download the latest version at the time of writing it was flashnul-1rc1.
#* Download and Extract the application from archive.
#* Click Start button > All Programs > Accessories > Command Prompt, right click on it and Run as Administrator.
#* Run the flashnul with argument:
C:/flashnul/flashnul.exe -p
#* Flashnul will tell you something like:

Avaible physical drives:
0 size = 250059350016 (232 Gb)
1 size = 1990197248 (1898 Mb)

Avaible logical disks:
C:\
D:\
F:\
G:\
H:\

Press ENTER to exit.

'''SDCARD number is on left! In my case it is number 1'''

#* Now we will use Load argument:
C:/flashnul/flashnul.exe 1 -L C:/debian6/debian6-19-04-2012.img
where '''<Path to flashnul directory>'''flashnul.exe '''<device number>''' -L '''<img file path>'''

#* Flashnul will give you a device summary and proceed caution, have a quick scan through the information to make sure you have selected the correct device, then type yes and press enter.
#* If you get a access denied error, try re-plugging the SD card.
#* If you still get a access denied error, try substitute the device number with the drive letter followed by a colon. Eg:
C:/flashnul/flashnul.exe H: -L C:/debian6/debian6-19-04-2012.img

I hope that this will help someone :) (I didn't test this created SDcard on Pi, yet because I still doesn't have it in my hands :( )

==Copying an image to the SD Card in Mac OSx==

# Download the image from a mirror or torrent
#* http://www.raspberrypi.org/downloads
# Verify if the the hash key is the same (optional), in the terminal run:
#* '''shasum ~/Downloads/debian6-13-04-2012.zip'''
# Extract the image:
#* '''unzip ~/Downloads/debian6-13-04-2012.zip'''
#* ''(or: just double click the zip, it will extract automatically)''
# From the terminal run '''df -h'''
# Connect the sdcard reader with the sdcard inside
# Run '''df -h''' again and look for the new device that wasn't listed last time. Record the device name of the filesystem's partition, e.g. '''/dev/disk1s1'''
# Unmount the partition so that you will be allowed to overwrite the disk:
#* '''diskutil unmount /dev/disk1s1'''
#* ''(or: open Disk Utility and unmount the partition of the sdcard (do not eject it, or you have to reconnect it))''
# Translate the device name of the partition into the raw device for the entire disk, by missing out the final "s1" and replacing "disk" with "rdisk":
#* e.g. '''/dev/disk1s1''' => '''/dev/rdisk1'''
# In the terminal write the image to the card with this command, using the raw disk device name from above:
#* '''dd bs=1m if=~/Downloads/debian6-13-04-2012/debian6-13-04-2012.img of=/dev/rdisk1'''
# After the dd command finishes, eject the card:
#* '''diskutil eject /dev/rdisk1'''
#* ''(or: open Disk Utility and eject the sdcard)''
# Insert it in the raspberry pi, and have fun

==Copying an image to the SD Card in Linux (command line)==

# Download the zip file containing the image from a mirror or torrent
#* http://www.raspberrypi.org/downloads
# Verify if the the hash key of the zip file is the same as shown on the downloads page (optional). Assuming that you put the zip file in your home directory (~/), in the terminal run:
#* '''sha1sum ~/debian6-13-04-2012.zip'''
#* This will print out a long hex number which should match the "SHA-1" line for the SD image you have downloaded
# Extract the image, with
#* '''unzip ~/debian6-13-04-2012.zip'''
# Run '''df''' to see what devices are currently mounted
# Connect the sdcard reader with the sdcard inside
# Run '''df''' again. The device that wasn't there last time is your SD card. The left column gives the device name of your SD card. It will be listed as something like "/dev/mmcblk0p1" or "/dev/sdd1". The last part ("p1" or "1" respectively) is the partition number, but you want to write to the whole SD card, not just one partition, so you need to remove that part from the name (getting for example "/dev/mmcblk0" or "/dev/sdd") as the device for the whole SD card. Note that the SD card can show up more than once in the output of df: in fact it will if you have previously written a Raspberry Pi image to this SD card, because the RPi SD images have more than one partition.
# Now that you've noted what the device name is, you need to unmount it so that files can't be read or written to the SD card while you are copying over the SD image. So run the command below, replacing "/dev/sdd1" with whatever your SD card's device name is (including the partition number)
#* '''umount /dev/sdd1'''
#* If your SD card shows up more than once in the output of df due to having multiple partitions on the SD card, you should unmount all of these partitions.
# In the terminal write the image to the card with this command, making sure you replace the input file '''if=''' argument with the path to your .img file, and the "/dev/sdd" in the output file '''of=''' argument with the right device name (this is very important: you can trash the hard drive on your computer if you get the wrong device name). Make sure the device name is the name of the whole SD card as described above, not just a partition of it (for example, sdd, not sdds1 or sddp1, or mmcblk0 not mmcblk0p1)
#* '''dd bs=1M if=~/debian6-13-04-2012/debian6-13-04-2012.img of=/dev/sdd'''
#* Note that if you are not logged in as root you will need to prefix this with '''sudo '''
# Remove SD card from card reader, insert it in the Raspberry Pi, and have fun

==Copying an image to the SD Card in Linux (graphical interface)==
If you are using Ubuntu and hesitate to use the terminal, you can use the ImageWriter tool (nice graphical user interface) to write the .img file to the SD card.

# Download the zip file containing the image from a mirror or torrent
#* http://www.raspberrypi.org/downloads
# Right click the zip file and select "Extract here"
# Insert the SD card into your computer or connect the SD card reader with the SD card inside
# Install the ImageWriter tool from the Ubuntu Software Center
# Launch the ImageWriter tool (it needs your administrative password)
# Select the image file (example debian6-13-04-2012.img) to be written to the SD card
# Select the target device to write the image to (your device will be something like "/dev/mmcblk0" or "/dev/sdc")
# Click the "Write do device button"
# Wait for the process to finish and then insert the SD card in the Raspberry Pi

=Manually resizing the SD card partitions (Optional)=
The SD card image is sized for a 2GB card. The Fedora Remix will automatically resize the partitions on the card during the first boot. The Debian version won't, so you'll have to do it manually. It's much easier if you do this on another machine, as the SD card can't be mounted when you do this.

==Manually resizing the SD card on Linux==
Following on from the instructions above, keep the newly-written SD card in the card reader, but unmounted. We'll use the <code>parted</code> (partition editor) tool to resize the partitions.
* Use parted to examine the card
$ sudo parted /dev/sdd
(parted) unit chs
(parted) print
Disk /dev/sdd: 121535,3,31
Sector size (logical/physical): 512B/512B
BIOS cylinder,head,sector geometry: 121536,4,32. Each cylinder is 65.5kB.
Partition Table: msdos

Number Start End Type File system Flags
1 16,0,0 1215,3,31 primary fat32 lba
2 1232,0,0 26671,3,31 primary ext4
3 26688,0,0 29743,3,31 primary linux-swap(v1)
: This shows how my SD card was formatted after writing the image. Notice that nothing uses the card from end of 'cylinder' 29743 to the card's maximum at 121535.
: Partition 1 is the boot partition: we'll leave that alone. Partition 2 is the root partition, which we'll grow to fill most of the card. Partition 3 is the swap space, which needs to be moved to the end of the card.
* Move the swap partition (you'll have to adjust the numbers so that the end of partition 3 is at the end cylinder/head/sector of the card)
(parted) move 3 118479,0,0
* Now grow the root partition. This involves removing the partition, re-creating it, then using <code>resize2fs</code> to grow the filesystem to fill the partition. It won't destroy any data.
(parted) rm 2
(parted) mkpart primary 1232,0,0 118478,3,31
(parted) quit
: Note that the starting address of the new partition is identical to its original value, and the ending address is immediately before the start of the swap partition.
* Now clean and resize the root partition
$ sudo e2fsck -f /dev/sdd2
: (allow it to add lost-and-found)
$ sudo resize2fs /dev/sdd2
* Then put the card in the RPi and boot. You end up with a 7Gb partition to use.

==About==
[[File:RpiFront.jpg|300px|thumb|right|The Rpi beta board (model B)]]

The Raspberry Pi (short: RPi or RasPi) is an ultra-low-cost credit-card sized Linux computer which was conceived with the primary goal of teaching computer programming to children. It was developed by the [http://www.raspberrypi.org Raspberry Pi Foundation], which is a UK registered charity (Registration Number 1129409). The foundation exists to promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing. We expect this computer to have many other applications both in the developed and the developing world ([[RPi_Philosophy|Read more]]).

* You can get the latest news from the [http://www.raspberrypi.org Foundation Home Page], the [http://twitter.com/intent/user?screen_name=Raspberry_Pi Twitter Feed] or in the [http://www.raspberrypi.org/forum/general-discussion/news-articles-and-blog-posts-about-raspberry-pi forums].
* For Raspberry Pi frequently asked questions see the [[R-Pi FAQ]] or the [http://www.raspberrypi.org/?page_id=8 Raspberry Pi Foundation's FAQ] page.
* Products are RoHS, CE, FCC, CTick and CSA compliant. Please contact the distributor from whom you purchased your Raspberry Pi device for details regarding WEEE in your country.
* Expected cost: ~16GBP or 25USD Model A, ~23GBP or 35USD for Model B. For information about availability and shipping see the [[RPi Buying Guide | Buying Guide]].

R-Pi Troubleshooting

2012-04-28T08:23:27Z

Linker3000: /* General / Formatting */

Back to the [[R-Pi Hub|Hub]].

[[Category:RaspberryPi]]
This page lists the most common problems and suggests some solutions.

==Power / Start-up==
A good power supply that will supply 5V is vital. There is more information about [[RPi_Hardware#Power|power supplies and troubleshooting]].
===Red power LED does not light, nothing on display===
The power is not properly connected.

===Red power LED is on, green LED does not flash, nothing on display===
The Raspberry Pi cannot find a valid image on the SD card. Check that you have correctly written a Raspberry Pi image to the card. See also, [[RPi_VerifiedPeripherals#SD_cards|Known SD Cards]].

===Raspberry Pi shuts down soon after booting up===
This is caused by a power supply with too low voltage or too high voltage.
Or it could be the cable. See: [[On_the_RPi_usb_power_cable]]

==Keyboard / Mouse / Input Devices==
===Keyboard randomly repeats key presses===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, most will have a label showing the voltage and mA requirements, they should be 5v 100mA each max, any more than this they must be used with a powered USB hub. Try unplugging every USB device except the keyboard (you should also note that some keyboards have built in hubs and can try to draw 1500mA (Pi can only handle 100mA per USB slot without a hub)).

==Memory Cards==
===General / Formatting===
If you are having problems setting up your memory card you might want to try erasing it completely - especially if it has been used elsewhere and still contains data / partitions.
* Windows and Mac users can download a formatting tool from the SD Association: https://www.sdcard.org/downloads/formatter_3/

* If you are preparing your SD card on a Linux-based system using the ''dd'' command, this operation will completely erase any existing data and partitions. Make sure you put the source image on the whole card, e.g. /dev/sdd, NOT /dev/sdd1.

==Networking==

===Ethernet connection is lost when a USB device is plugged in===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub. Some cheap USB hubs suck power from the Raspberry Pi even if a USB power supply is connected.

==Sound==
===Sound does not work with a HDMI monitor===
This is caused by some computer monitors which select DVI mode even if a HDMI cable is connected.

Enter the command
sudo nano /boot/config.txt

If this file is empty or does not contain the config_hdmi_boost parameter, add the following line
hdmi_drive=2

If this file already contains the hdmi_drive parameter, use the editor to change the value.

Save the edited file
Press Control-X
Press y
Press [enter]

After exiting the editor, restart using the command
sudo reboot

Note that you must use the correct reboot command to force a write of the edited file to the SD card.

===Sound does not work in some applications===
Device drivers for sound are still being developed. Please wait for the community to improve the situation.

==Display==
===Video does not play or plays very slowly===
It must be H264 or XVID. Device drivers for video are still being developed. The XMBC distribution is the only distribution with good video support at the moment. Please wait for the community to improve the situation.

===Can only get 800x480 resolution in LXDE (Arch linux)===
Known issue with distro package as of 17-Apri-2012 - there's some missing boot config info. Creating a suitable cmdline.txt fixes it - type the following at the Raspberry Pi command line:

<pre>
sudo echo "dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait" >/boot/cmdline.txt
</pre>

===Interference visible on a HDMI or DVI monitor===
This may be caused by loss of signal on long video cables. The signal level may be increased by changing a configuration parameter.
[[File:RPi_HDMI_interference.jpg|600px]]

Enter the command
sudo nano /boot/config.txt

If this file is empty or does not contain the config_hdmi_boost parameter, add the following line
config_hdmi_boost=4

If this file already contains the config_hdmi_boost parameter, use the editor to change the value.

Save the edited file
Press Control-X
Press y
Press [enter]

After exiting the editor, restart using the command
sudo reboot

You may experiment with different values of config_hdmi_boost. Value 1 is used for very short cables, value 7 is used for very long cables. Note that you must use the correct reboot command to force a write of the edited file to the SD card.

==GPIO==
To be added.

==Troubleshooting power problems==
If you think you have a problem with your power supply, it is a good idea to check the actual voltage
on the Raspberry Pi circuit board. Two test points labelled TP1 and TP2 are provided on the circuit board
to facilitate voltage measurements.

Use a multimeter which is set to the range 20 volts DC (or 20v =). You should see a voltage between 4.75 and 5.25 volts. Anything outside this range indicates that you have a problem with your power supply or your power cable.

On the other hand, a multimeter displays the average voltage. If short power-burst-requirements on the 'pi are not adequately regulated by the power supply the Raspberry Pi might still have power problems even though the multimeter gives the OK.

R-Pi Troubleshooting

2012-04-19T16:20:01Z

Linker3000: /* Can only get 800x480 resolution in LXDE (Arch linux) */

Back to the [[R-Pi Hub|Hub]].

[[Category:RaspberryPi]]
This page lists the most common problems and suggests some solutions.

==Power / Start-up==
A good power supply that will supply 5V is vital. There is more information about power supplies and troubleshooting here http://elinux.org/RPi_Hardware#Power
===Red power LED does not light, nothing on display===
The power is not properly connected.

===Red power LED is on, green LED does not flash, nothing on display===
The Raspberry Pi cannot find a valid image on the SD card.

===Raspberry Pi shuts down soon after booting up===
This is caused by a power supply with too low voltage or too high voltage.

==Keyboard / Mouse / Input Devices==
===Keyboard randomly repeats key presses===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, most will have the voltage and mAh on the back of them, they should be 5v 100mAh each max, any more than this they must be used with a powered USB hub. Try unplugging every USB device except the keyboard (you should also note that some keyboards have built in hubs and can try to draw 1500mAh (Pi can only handle 100mAh per USB slot without a hub)).

==Memory Cards==
===General / Formatting===
If you are having problems setting up your memory card you might want to try erasing it completely - especially if it has been used elsewhere and still contains data / partitions. Windows and Mac users can download a formatting tool from the SD Association: https://www.sdcard.org/downloads/formatter_3/

==Networking==

===Ethernet connection is lost when a USB device is plugged in===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub. Some cheap USB hubs suck power from the Raspberry Pi even if a USB power supply is connected.

==Sound==
===Sound does not work===
Device drivers for sound are still being developed. Please wait for the community to improve the situation.

==Display==
===Video does not play or plays very slowly===
Device drivers for video are still being developed. The XMBC distribution is the only distribution with good video support at the moment. Please wait for the community to improve the situation.

===Can only get 800x480 resolution in LXDE (Arch linux)===
Known issue with distro package as of 17-Apri-2012 - there's some missing boot config info. Creating a suitable cmdline.txt fixes it - type the following at the Raspberry Pi command line:

<pre>
sudo echo "dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait" >/boot/cmdline.txt

==Notes==

19-Apr-2012: Now that the Model B board is shipping, details added should relate to this board and the default Debian distribution unless stated otherwise. A suggested suffix markup scheme is as follows:

* (A) - Relates to model A production board
* (B) - Relates to model B production board
* (!) - Information from alpha board days
* No markup - relates to all production boards

''Discuss: [http://www.raspberrypi.org/forum/?mingleforumaction=viewtopic&t=247 http://www.raspberrypi.org/forum/?mingleforumaction=viewtopic&t=247]''

If you are adding to a product list it would help clarity if entries are kept/added in alphabetical order.

'''''Adding peripherals may increase the loading on the power supply to your board and this, in turn, may affect the voltage presented to the RPi. If the RPi's supply voltage falls below a certain value (anecdotally stated as around 4.75V), or it begins to fluctuate, your setup may become unstable. There is a [http://elinux.org/RPi_Hardware#Power Wiki section about this issue] which is worth a read.'''''

'''Not working'''

These adapters do '''NOT''' work, or need further investigation to make them work:

''(empty at the moment)''

== USB Bluetooth adapters ==

== USB Ethernet adapters ==

== USB IR Receivers==

== USB TV Tuners==

== USB UART adapters ==
The USB UART adapter is used to access the serial console of the Raspberry Pi from a development host such as a laptop or desktop PC. The USB end connects to the PC and the UART header end connects to the USB. While it is possible to connect the USB end to another Raspberry Pi, this configuration has not been tested unless explicitly mentioned against an individual entry below.

== Power adapters ==
* HTC
** TCP-300 Single port USB mains phone charger 5v 1A (B)
* Stontronics
** S2097ST switching PSU, 7.5V 1.6A (!) '''Note that the power connector and voltage requirements for production boards are completely different'''

== SD cards ==

Note that manufacturers change their designs over time, even as the specs stay the same. (E.g. an ACME 8 GB class 4 card manufactured in 2011 might work, while one manufactured in 2012 might not.)
For this reason, please specify product numbers in the lists below, when possible.

===Working Cards===
* Adata Class 10 8GB (AUSDH8GCL10-R)
* Dane-Elec 16Gb class 4
* Integral Ultima Pro 16GB Class 10 (20MB/s)
* Kingston SD 2GB (no class mentioned)
* Kingston SDHC 8GB class 4
* Samsung SDHC 8GB
* SanDisk Ultra 2GB Class 4 (15MB/s)
* SanDisk Ultra II SD 2GB class 4
* SanDisk 2GB (non sdhc but with a circle 2), writes at 3.5 Mb/s
* SanDisk 2GB, white "SanDisk for Wii" branded, no class mentioned
* SanDisk 8GB SDHC (class 4); writes at ~1.5MB/s
* SanDisk 16GB SDHC (class 4)
* Transcend SDHC 16GB class 10
* Transcend SDHC 8GB class 6
* Transcend SDHD 4GB class 4 - we've found these to work without any errors and offer reasonable performance
Known good (and pre-loaded) cards will be available for sale from the RPi foundation at a ''later'' date (TBA).

== works, but... ==

* Kingston SDHC 4GB class 4 (works but gets mmc errors: mmc0: final write to SD card still running) Russel King might have a kernel patch for this problem.

===Problem Cards===

There are issues with most Class 10 SDHC cards, apparently due to a bug in the Broadcom bootloader.[http://www.raspberrypi.org/forum/general-discussion/class-10-sd-cards-on-the-production-boards/page-3/#p39181]

* Patriot Class 10 8GB (PSF8GSDHC10)
* SanDisk Ultra Class 6 8GB (B11201421964G)

The usual warnings against less reputable sellers (such as Ebay merchants) apply.

Note that the following error is sometimes accompanied with a non-working SD card after booting (on Debian):

mmc0: timeout waiting for hardware interrupt

[[File:RpiFront.jpg|300px|thumb|right|The Rpi beta board (model B)]]

'''The Raspberry Pi wiki pages on this site are a community work - the Raspberry Pi Foundation is not responsible for content on these pages.'''

The Raspberry Pi (short: RPi or RasPi) is an ultra-low-cost credit-card sized Linux computer which was conceived with the primary goal of teaching computer programming to children. It was developed by the [http://www.raspberrypi.org Raspberry Pi Foundation], which is a UK registered charity (Registration Number 1129409). The foundation exists to promote the study of computer science and related topics, especially at school level, and to put the fun back into learning computing. We expect this computer to have many other applications both in the developed and the developing world.

R-Pi Troubleshooting

2012-04-19T09:29:07Z

Linker3000:

Back to the [[R-Pi Hub|Hub]].

This page lists the most common problems and suggests some solutions.

==Power / Start-up==
===Red power LED does not light, nothing on display===
The power is not properly connected.

===Red power LED is on, green LED does not flash, nothing on display===
The Raspberry Pi cannot find a valid image on the SD card.

===Raspberry Pi shuts down soon after booting up===
This is caused by a power supply with too low voltage or too high voltage.

==Keyboard / Mouse / Input Devices==
===Keyboard randomly repeats key presses===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub. Try unplugging every USB device except the keyboard.

==Networking==

===Ethernet connection is lost when a USB device is plugged in===
This is caused by inadequate power. Use a good power supply and a good power cable. Some USB devices require a lot of power, so they must be used with a powered USB hub. Some cheap USB hubs suck power from the Raspberry Pi even if a USB power supply is connected.

==Sound==
===Sound does not work===
Device drivers for sound are still being developed. Please wait for the community to improve the situation.

==Display==
===Video does not play or plays very slowly===
Device drivers for video are still being developed. The XMBC distribution is the only distribution with good video support at the moment. Please wait for the community to improve the situation.

===Can only get 800x480 resolution in LXDE (Arch linux)===
Known issue with distro package as of 17-Apri-2012 - there's some missing boot config info. Creating a suitable cmdline.txt fixes it - type the following at a command line:

<pre>
echo "dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait" >/boot/cmdline.txt

'''Not working'''

These adapters do '''NOT''' work, or need further investigation to make them work:

''(empty at the moment)''

== USB Bluetooth adapters ==

== USB Ethernet adapters ==

== USB IR Receivers==

== USB TV Tuners==

== USB UART adapters ==
The USB UART adapter is used to access the serial console of the Raspberry Pi from a development host such as a laptop or desktop PC. The USB end connects to the PC and the UART header end connects to the USB. While it is possible to connect the USB end to another Raspberry Pi, this configuration has not been tested unless explicitly mentioned against an individual entry below.

== Power adapters ==
* HTC
** TCP-300 Single port USB mains phone charger 5v 1A (B)
* Stontronics
** S2097ST switching PSU, 7.5V 1.6A (!) '''Note that the power connector and voltage requirements for production boards are completely different'''

== SD cards ==

Note that manufacturers change their designs over time, even as the specs stay the same. (E.g. an ACME 8 GB class 4 card manufactured in 2011 might work, while one manufactured in 2012 might not.)
For this reason, please specify product numbers in the lists below, when possible.

===Working Cards===
* Adata Class 10 8GB (AUSDH8GCL10-R)
* Dane-Elec 16Gb class 4
* Integral Ultima Pro 16GB Class 10 (20MB/s)
* Kingston SDHC 8GB class 4
* Kingston SD 2GB (no class mentioned)
* Kingston SDHC 8GB class 4
* Samsung SDHC 8GB
* SanDisk Ultra 2GB Class 4 (15MB/s)
* SanDisk Ultra II SD 2GB class 4
* SanDisk 2GB (non sdhc but with a circle 2), writes at 3.5 Mb/s
* SanDisk 2GB, white "SanDisk for Wii" branded, no class mentioned
* SanDisk 8GB SDHC (class 4); writes at ~1.5MB/s
* SanDisk 16GB SDHC (class 4)
* Transcend SDHC 16GB class 10
* Transcend SDHC 8GB class 6
* Transcend SDHD 4GB class 4 - we've found these to work without any errors and offer reasonable performance
Known good (and pre-loaded) cards will be available for sale from the RPi foundation at a ''later'' date (TBA).

== works, but... ==

* Kingston SDHC 4GB class 4 (works but gets mmc errors: mmc0: final write to SD card still running) Russel King might have a kernel patch for this problem.

===Problem Cards===

There are issues with most Class 10 SDHC cards, apparently due to a bug in the Broadcom bootloader.[http://www.raspberrypi.org/forum/general-discussion/class-10-sd-cards-on-the-production-boards/page-3/#p39181]

* Patriot Class 10 8GB (PSF8GSDHC10)
* SanDisk Ultra Class 6 8GB (B11201421964G)

The usual warnings against less reputable sellers (such as Ebay merchants) apply.

Note that the following error is sometimes accompanied with a non-working SD card after booting (on Debian):

mmc0: timeout waiting for hardware interrupt

== USB Bluetooth adapters ==

== USB Ethernet adapters ==

== USB IR Receivers==

== USB TV Tuners==

== USB UART adapters ==
The USB UART adapter is used to access the serial console of the Raspberry Pi from a development host such as a laptop or desktop PC. The USB end connects to the PC and the UART header end connects to the USB. While it is possible to connect the USB end to another Raspberry Pi, this configuration has not been tested unless explicitly mentioned against an individual entry below.

== Power adapters ==
* Alpha board: Stontronics S2097ST switching PSU, 7.5V 1.6A

== SD cards ==

Note that manufacturers change their designs over time, even as the specs stay the same. (E.g. an ACME 8 GB class 4 card manufactured in 2011 might work, while one manufactured in 2012 might not.)
For this reason, please specify product numbers in the lists below, when possible.

===Working Cards===
* Adata Class 10 8GB (AUSDH8GCL10-R)
* Dane-Elec 16Gb class 4
* Integral Ultima Pro 16GB Class 10 (20MB/s)

== works, but... ==

* Kingston SDHC 4GB class 4 (works but gets mmc errors: mmc0: final write to SD card still running) Russel King might have a kernel patch for this problem.

===Problem Cards===

There are issues with most Class 10 SDHC cards, apparently due to a bug in the Broadcom bootloader.[http://www.raspberrypi.org/forum/general-discussion/class-10-sd-cards-on-the-production-boards/page-3/#p39181]

* Patriot Class 10 8GB (PSF8GSDHC10)
* SanDisk Ultra Class 6 8GB (B11201421964G)

The usual warnings against less reputable sellers (such as Ebay merchants) apply.

Note that the following error is sometimes accompanied with a non-working SD card after booting (on Debian):

mmc0: timeout waiting for hardware interrupt

===Wireless: TP-Link TL-WN722N USB wireless adapter (Debian 6)===

See also:

http://www.element14.com/community/docs/DOC-44703/l/raspberry-pi-wifi-adapter-testing

http://omer.me/2012/04/setting-up-wireless-networks-under-debian-on-raspberry-pi/

This will serve as a general guide for USB wireless devices but may need modifying for your specific one.

* Edit /etc/apt/sources.list to add the non-free archive and backports (eg: sudo vi /etc/apt/sources.list):

<pre>
deb http://ftp.us.debian.org/debian/ squeeze main non-free
deb http://security.debian.org/ squeeze/updates main non-free
deb http://ftp.us.debian.org/debian/ squeeze-updates main non-free
deb http://backports.debian.org/debian-backports squeeze-backports main non-free
</pre>

* Update the package cache:

<pre>
sudo apt-get update
</pre>

* Download the wifi utils:

<pre>
sudo apt-get install wireless-tools usbutils
</pre>

* Download the required firmware and put it in the correct location - you may not need to do this for your adapter or you may need different firmware - see below.

<pre>
sudo apt-get install firmware-atheros
sudo wget http://linuxwireless.org/download/htc_fw/1.3/htc_9271.fw
sudo cp htc_9271.fw /lib/firmware
</pre>

* Add adapter definition to network config - eg: sudo vi /etc/network/interfaces - add the wlan0 section:

<pre>
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

auto lo

iface lo inet loopback
iface eth0 inet dhcp

# The wireless interface
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa.conf
</pre>

* Plug in adapter

* Confirm adapter is present:

<pre>
root@raspberrypi:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
</pre>

* Scan your network to see what wireless access points can be seen. You may need to do this to identify your network's SSID (name), but it also confirms that the wifi dongle is doing something. The first command just lists the SSIDs found, the second tells you probably more than you ever want to know:

<pre>
sudo iwlist wlan0 scan | grep ESSID
</pre>
or
<pre>
sudo iwlist wlan0 scan
</pre>

* Create the wpa.conf file - eg: sudo vi /etc/wpa.conf:

'''Note: The ssid is case sensitive - if your WLAN's SSID is MYLAN, using "mylan" will not work - you won't connect!'''

<pre>
network={
ssid="NETWORK-SSID"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="YOUR-WLAN-PASSWORD"
}
</pre>

* Start the adapter

<pre>
sudo ifup wlan0
</pre>

* Double-check whether you are connected - below the WLAN interface has been given an IP address - looks good!

<pre>
root@raspberrypi:~# ifconfig
eth0 Link encap:Ethernet HWaddr b8:27:eb:76:7e:2e

</pre>

If you are now connected, well done! If not, check your editing and also have a look at the output of ''dmesg'' to see if you have any error messages. You can also view the system log for messages - for example: ''sudo cat /var/log/messages | more''

==Notes==

'''USB interrupt/dma system debug messages'''

Firing up the TP-Link USB WLAN interface generates a lot of debug messages in the system log like this:

DEBUG:handle_hc_chhltd_intr_dma:: XactErr without NYET/NAK/ACK

Things may calm down a bit if the following file is created in /etc/modprobe.d (eg: sudo vi /etc/modprobe.d/smscnonturbo.conf) and then the RPi rebooted:

'''smscnonturbo.conf:'''
<pre>
options smsc95xx turbo_mode=N
</pre>

This fix may slow down wired LAN performance but help with wireless and reduce the frequency of the debug messages - YMMV. If you want to undo this fix, just delete the file (sudo rm /etc/modprobe.d/smscnonturbo.conf) and reboot.

'''Firmware requirements'''

If no wlanx device is shown, you might need to download firmware for your USB wifi device (or track down other compatible drivers if they are available). To confirm this, check the dmesg output when you plug in your adapter - typing ''dmesg'' at the command prompt may be sufficient - and look for information related to your adapter - the example ''dmesg'' output below shows what is seen in the event of the TP-Link firmware not being present - notice that the name of the required firmware file is given (htc_9271.fw), the driver name (ath9k_htc) and an error -22 message:

<pre>
usb 1-1.2.4.2: ath9k_htc: Firmware - htc_9271.fw not found
ath9k_htc: probe of 1-1.2.4.2:1.0 failed with error -22
usbcore: registered new interface driver ath9k_htc
</pre>

Armed with this information, try a web search for 'debian 6' and the name of the driver or driver file and/or head over to http://linuxwireless.org. Also check the links at the top of this page.

'''Power requirements'''

If you experience erratic network, keyboard, mouse or Raspberry Pi operation when using a USB wifi dongle, check that whatever is powering your RPi and/or USB hub can deliver sufficient current for everything that's connected together. The first setup tried with the TP-Link adapter had it, a keyboard, mouse and the RPi all connected to a Trust 7-port powered USB hub with a 5V 2A power supply, but in this configuration the mouse stopped working. In this case, the fix was to power the RPi from a separate 5V 1A phone power adapter.

===Wireless: TP-Link TL-WN722N USB wireless adapter (Debian 6)===

http://www.element14.com/community/docs/DOC-44703/l/raspberry-pi-wifi-adapter-testing

http://omer.me/2012/04/setting-up-wireless-networks-under-debian-on-raspberry-pi/

This will serve as a general guide for USB wireless devices but may need modifying for your specific one.

* Edit /etc/apt/sources.list to add the non-free archive and backports (eg: sudo vi /etc/apt/sources.list):

<pre>
deb http://ftp.us.debian.org/debian/ squeeze main non-free
deb http://security.debian.org/ squeeze/updates main non-free
deb http://ftp.us.debian.org/debian/ squeeze-updates main non-free
deb http://backports.debian.org/debian-backports squeeze-backports main non-free
</pre>

* Update the package cache:

<pre>
sudo apt-get update
</pre>

* Download the wifi utils:

<pre>
sudo apt-get install wireless-tools usbutils
</pre>

* Download the required firmware and put it in the correct location - you may not need to do this for your adapter or you may need different firmware - see below.

<pre>
sudo apt-get install firmware-atheros
sudo wget http://linuxwireless.org/download/htc_fw/1.3/htc_9271.fw
sudo cp htc_9271.fw /lib/firmware
</pre>

* Add adapter definition to network config - eg: sudo vi /etc/network/interfaces - add the wlan0 section:

<pre>
# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

auto lo

iface lo inet loopback
iface eth0 inet dhcp

# The wireless interface
auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa.conf
</pre>

* Plug in adapter

* Confirm adapter is present:

<pre>
root@raspberrypi:~# iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
</pre>

* Scan your network to see what wireless access points can be seen. You may need to do this to identify your network's SSID (name), but it also confirms that the wifi dongle is doing something. The first command just lists the SSIDs found, the second tells you probably more than you ever want to know:

<pre>
sudo iwlist wlan0 scan | grep ESSID
</pre>
or
<pre>
sudo iwlist wlan0 scan
</pre>

* Create the wpa.conf file - eg: sudo vi /etc/wpa.conf:

'''Note: The ssid is case sensitive - if your WLAN's SSID is MYLAN, using "mylan" will not work - you won't connect!'''

<pre>
network={
ssid="NETWORK-SSID"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
psk="YOUR-WLAN-PASSWORD"
}
</pre>

* Start the adapter

<pre>
sudo ifup wlan0
</pre>

* Double-check whether you are connected - below the WLAN interface has been given an IP address - looks good!

<pre>
root@raspberrypi:~# ifconfig
eth0 Link encap:Ethernet HWaddr b8:27:eb:76:7e:2e

RX bytes:2260 (2.2 KiB) TX bytes:1542 (1.5 KiB)
</pre>

If you are now connected, well done! If not, check your editing and also have a look at the output of ''dmesg'' to see if you have any error messages. You can also view the system log for messages - for example: ''sudo cat /var/log/messages | more''

'''Firmware requirements'''

If no wlanx device is shown, you might need to download firmware for your USB wifi device (or track down other compatible drivers if they are available). To confirm this, check the dmesg output when you plug in your adapter - typing ''dmesg'' at the command prompt may be sufficient - and look for information related to your adapter - the example ''dmesg'' output below shows what is seen in the event of the TP-Link firmware not being present - notice that the name of the required firmware file is given (htc_9271.fw), the driver name (ath9k_htc) and an error -22 message:

<pre>
usb 1-1.2.4.2: ath9k_htc: Firmware - htc_9271.fw not found
ath9k_htc: probe of 1-1.2.4.2:1.0 failed with error -22
usbcore: registered new interface driver ath9k_htc
</pre>

Armed with this information, try a web search for 'debian 6' and the name of the driver or driver file and/or head over to http://linuxwireless.org. Also check the links at the top of this page.
