IMPORTANT For USB devices other than a mouse and a simple wired keyboard (for USB devices drawing more than 100mA) a powered USB hub is strongly recommended. A technical discussion as to why can be found here. Specifically the RPi's built in USB hub is designed only for "Single current unit" USB devices. Note that when using Revision 2 (or later) boards the problem has been mitigated somewhat with the removal of the USB polyfuses, still due to the limited current the PI can provide to USB devices, due to its main polyfuse, its still recommended to use a hub for all USB peripherals requiring more than 100mA.
Other, optional equipment includes:
- SD card reader - if you need to prepare your own SD card
- Power Supply Switch - if you want an easy way to cycle power
装置使用一个 Micro USB 连接来为其供电(仅供电引脚连接 - 所以此连接将不会传输数据). 一个标准的带有 micro-USB 连接的现代手机充电器即可使用,但是需要在 5v 时能至少提供 700mA 电流.仔细检查你的供电设备等级,及 当心廉价仿制品!.
Pi Hut 提供 5V 1500mA 供电,专为Raspberry Pi制造.此处有三个种类 :
- 电脑 USB 端口或带供电 USB hub (将取决于供电输出)
- 带有 USB 端口的特殊墙壁插座
- 手机后备电池 (将取决于供电输出) (理论上 - 需认证)
- 带有内置 USB 的现代电视 (例如, 已经被展示可工作于 Sony KDL-40HX723 和 KDL-55NX813)
- 带有 USB 端口的 Internet 路由 (BT Home Hub 3 看起来使Pi运行的很好)
要使用以上电源,你将要需要一个 USB A '公口' 转 USB micro '母口' 线 - 它们通常是手机的数据线.
Additionally, the Raspberry Pi does not have the functionality of an on/off switch like traditionally seen on a PC. Pi Supply have for sale an add on board that introduces this functionality, allowing you to easily manage power on your Raspberry Pi, without wearing out your back, or the micro-USB socket on the Pi. It also includes a safe shutdown switch to avoid corruption of your SD card.
For detailed information about power requirements see RPi Hardware - Power.
Want to use your Raspberry Pi on the go? Then you need a Portable Power Pack! The rechargeable battery pack allows you to use your Raspberry Pi anywhere. Available from The Pi Hut - Portable Power Pack for the Raspberry Pi
RPi没有内置存储或内建启动代码,所以它需要一个SD卡设置用来启动RPi并加载操作系统.你应当阅读RPi Easy SD Card Setup页面来获得相关指引,包括购买一个已预装卡或创建一个你自己的安装的SD卡
键盘 & 鼠标
记住 Model A 仅有一个USB端口,Model B 仅有两个(通常键盘和鼠标需要各用一个USB端口) - 见下面 USB Hub .
如需检查你的键盘和鼠标与Linux是否兼容,见 RPi Verified Peripherals.
RPi有两种显示连接选择,HDMI (高分辨率) 和 Composite (低分辨率).
- 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. Note that the RCA output is composite video, not RF, so it cannot be connected directly to the antenna input of a TV, you need to connected it the the yellow video input connector, or to the SCART input using a RCA to SCART plug, (adapter).
When using composite video, audio is available from a 3.5mm (1/8 inch) socket, and can be sent to your TV, or to an amplifier. To send audio to your TV, you will need a cable which adapts from 3.5mm to double (red and white) RCA connectors. These red and white can go into the red and white RCA plug inputs of a TV, or a stereo set, or to the above mentioned RCA to SCART plug. Another option for audio (when not using HDMI) is to connect the 3.5mm jackplug to an amplified speakerset. Do not connect the 3.5 mm jack directly to a headset, as the 3.5 mm audio output isn't suitable to drive headsets, only amplifier inputs. Attaching a low impedance load, (such as a headset) to the stereo audio output may lead to distorted sound.
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). Problems have been reported with converters if the power supply is not adequate and the converter is not powered from its own power supply.
The Pi Hut offer two adapters that will allow the Raspberry Pi to be used with multiple monitor formats
For detailed information see Rpi Screens.
You will probably need a number of cables in order to connect your RPi up.
- Micro-B USB Power Cable (see above) picture. This has to be a high quality one.
- HDMI-A picture or Composite cable picture, plus DVI adaptor picture or SCART adaptor picture if required, to connect your RPi to the Display/Monitor/TV of your choice.
- Audio cable picture, this is not needed if you use a HDMI TV/monitor.
- Ethernet/LAN Cable (see below) 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: Why you don't need to spend more than £2 on an HDMI cable
网络 / Internet 连通
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).
Support for USB WiFi adaptors will vary - see RPi Verified Peripherals.
Note: If a Netgear router has a blank in the fourth box of the subnet mask, raspbian will interpret that as a 255, not as a '0' like Ubuntu. This will give you a subnet mask of 255.255.255.255 and a useless network connection. Changing the router's setting to put a '0' in the last field and reinitializing the network will fix this.
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. The USB ports are fused at about 140ma each without an additional external power source. This not enough to power a hard drive, and you may even have trouble powering wireless adapters and other peripherals. There is enough current out there, however, for mice and most keyboards. (see 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.
通过使用一个预装的,电池供电的 '实时时钟'(RTC),笔记本和电脑在断电后能保持时间.然而,实时时钟模块没有被包含在Raspberry Pi中.为了保持时间,Raspberry Pi自动依赖以太网或WiFi从互联网更新日期和时间.对于没有互联网连接的项目,你可以考虑添加一个低成本的电池供电RTC来帮助你的Pi保持时间.
Afterthought Software have released a 'Plug and Play' Real Time Clock designed specifically for the Raspberry Pi which, unlike other RTC's available, plugs directly in to the Raspberry Pi's GPIO Ports. The unit is available from ModMyPi and comes complete with an easy to follow Installation Guide.
If you need to install the Operating System on your own SD Card you will need another PC, Laptop or Mac to do so (or get a friend or local group to do it for you). If you are running headless, you also need one, though for a lot of uses (but not all) you can use a tablet or smart phone. This does include another Pi!
You can use the diagram to connect everything together using the following instructions:
- Plug the SD Card loaded with the Operating System into the Pi.
- If required, plug the USB keyboard and mouse into the Pi, perhaps via a USB Hub. Connect the Hub to power, if necessary.
- If required, plug the video cable into the display and into the Pi.
- Plug in your Network cable, or WiFi dongle, if required.
- Ensure that your USB Hub (if any) and display are working.
- With your screen on, plug the other end of the power source into the Pi.
- Plug the power source into the main socket, and switch it on.
- If connected to a display, the Pi should boot up and display messages on the screen.
- If running headless, it should boot up. When the leds have stopped flashing, connect to the Pi from the remote computer. Whether this works will depend on the operating system you are using; the Raspian Linux operating system is configured to allow SSH connections by default.
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).
If you use both a R-PI power supply and a powered hub, its recommended you connect them to the same switched power bar, and use the switch on the power bar to switch off both the R-PI and hub at the exact same time.
Also, always shutdown using the software shutdown function, not by pulling the plug. When not using a GUI, (with a GUI use the GUI command) you can use the command "sudo halt", and power off when all the LED's on the board (except the power LED) go off. This is especially important the first time you boot, as in the process the R-PI modifies the content of the SD-card, without a clean shutdown the contents of the card may be damaged.
The RPi may take a long time to boot when powered-on for the first time, so be patient, and cleanly shutdown afterwards, as described above!
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 Verified Peripherals.
Not a vital accessory for your RPi, but will help to reduce the CPU's temperature whilst under load. Available from The Pi Hut's Raspberry Pi Store, Etsy, ModMyPi (with lots of tips and tricks for reducing temperature in the reviews) or eBay
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 case should be considered, and there is a Rpi case thread on the forum. Cases are also available from The Pi Hut's Raspberry Pi Store,ModMyPi's Raspberry Pi Shop and MobileApp Systems.
For detailed information see Rpi Cases.
You may need an SD card reader to prepare an SD card, or read a second one, both for the Pi or the other computer if it does not have an integral SD card reader.
ModMyPi's Raspberry Pi Shop stocks a low cost (99p) SD Card Reader.
扩展 & 低级外设
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 RPi Projects, Guides & Tutorials section).
For detailed information see Rpi Low-level Peripherals.
