What’s a Raspberry Pi?
The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.
BUYING AND SHIPPING
Where can I buy one?
How many can I buy in one go?
How much will it cost?
The Model A will cost $25 and the Model B $35, plus local taxes.
How can I pay for it?
We will accept most major cards, PayPal, and offline payments.
What will I get when I buy one?
A Raspberry Pi. Leads, a power supply or SD cards are not included but will be able to be purchased after the current demand for Raspberry Pi boards is being satisfied by Premier Farnell/Element 14 and RS Components, (probably April 2012). You will eventually be able to buy preloaded SD cards too. The initial batches through Summer 2012 will not have a case.
Why is the price in US Dollars? You’re a UK company!
Will there be a buy-one-give-one program?
Yes. We plan to implement a program of this sort, but you can also just buy one if you prefer.
Will the device be available internationally?
Premier Farnell/Element 14 and RS Components distribute and ship world-wide via subsidiaries and partners in virtually every country. There have been some problems with information about pricing and availability being fully shared among some countries' local offices, but, they are being worked out with the primary distributors and should be resolved by mid-March 2012.
How much will it cost to ship to [country X]?
Premier Farnell/Element 14 and RS Components and their subsidiaries/partners will convey this information before orders are charged, and these costs may vary from country to country, which the Foundation cannot control.
Will there be a minimum order quantity?
The minimum order quantity will be one unit.
Do you accept pre-orders?
I want to be a Raspberry Pi reseller.
We are not taking requests for people to be resellers at the moment.
Can I join the mailing list?
You certainly can. Head to the home page, and you’ll see a form at the top right you can fill in. People who are signed up will get an e-mail as soon as we have confirmed a release date.
What’s the difference between Model A and Model B?
Model A has 256 MB of RAM, one USB port and no Ethernet (network connection). Model B has 256 MB RAM, two USB ports and a 100 Mbits/sec Ethernet port.
What are the dimensions of the Raspberry Pi?
What SoC are you using?
Why did you select the ARM11?
Cost and performance.
How powerful is it?
The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode.
The GPU is capable of 1 Gpixel/s, 1.5 Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure.
Will it overclock?
There’s a little overclocking headroom – most devices will run happily at 800MHz. There’s no BIOS per se, but we do support booting bare metal code, so something could be done.
Will it blend?
Yes. We have conducted extensive virtual simulations. No Raspberry Pis were harmed in the testing.
How does it boot?
Where’s the on / off switch?
To switch on: just plug it in!
To switch off: remove power.
Why is there no real time clock (RTC)?
Will you sell a self-assembly kit?
Can I add extra memory?
No. The RAM is a POP package on top of the SoC, so it’s not removable or swappable.
What hardware documentation will be available?
But I want documentation for <hardware X>!
Other documentation may be released in future but this will be at the Foundation’s discretion.
But I demand the documentation for the chip. Give it to me!
Why doesn’t the Raspberry Pi include <insert name> piece of hardware or <insert name> sort of port?
Can you test it to make sure that it is suitable for <X>?
How do I connect a mouse and keyboard?
Will it have a case?
Will it fit in an Altoids tin?
What display can I use?
Why is there no VGA support?
Is there a GPU binary?
Yes. The GPU binary also contains the first stage bootloader.
Can I add a touchscreen?
What is the usable temperature range?
The Raspberry Pi is built from commercial chips which are qualified to different temperature ranges; the LAN9512 is specified by the manufacturers being qualified from 0°C to 70°C, while the AP is qualified from -40°C to 85°C. You may well find that the board will work outside those temperatures, but we’re not qualifying the board itself to these extremes.
Is sound over HDMI supported?
What about standard audio in and out?
There’s a standard 3.5mm jack for audio out. You can add any supported USB microphone for audio in.
What are the power requirements?
The device is powered by 5v micro USB. You can read more about it here. Power supplies will be available at launch.
Can I run power Raspberry Pi from batteries as well as from a wall socket?
Yes. The device should run well off 4 x AA cells.
Is power over Ethernet (PoE) possible?
What operating system (OS) does it use?
We’ll be using Fedora as our recommended distribution. It’s straightforward to replace the root partition on the SD card with another ARM Linux distro if you want to use something else. The OS is stored on the SD card.
Does it have an official programming language?
By default, we’ll be supporting Python as the educational language.
Will it run WINE (or Windows, or other x86 software)?
What Linux distros will be supported at launch?
Will it run Android?
Will it run <insert name of program here>?
Will it run the new Windows 8 ARM version?
We are not partners with Microsoft, and their support would be required for porting Windows 8.
SD cards and storage
What happens if I brick the device?
You can restore the device by reflashing the SD card.
NETWORKING, USB AND WIRELESS
Does the device support networking? Is there Wi-Fi?
Will there be a WiFi option?
Why no Gigabit Ethernet?
The Ethernet is driven via USB 2.0, so the upstream bandwidth would not support Gigabit.
Does the device have support for any form of netbooting or Pxe?
No. However, it’s such a low-power device that we expect it to be left on much of the time!
How do you connect more than two USB devices?
Use a hub to increase the number of ports. Some keyboards have hubs built in which would work well.
What educational material will be available?
Once we launch, we hope that the community will help organizations like Computing at School put together teaching material such as lesson plans and resources and push this into schools. In due course, the foundation hopes to provide a system of prizes to give young people something to work towards.
There’s lots of discussion of educational uses and resources in our forums – come and have a chat!
