The Rpi bèta board (model B)

A Raspberry Pi (or short: Rpi) is a cheap credit-card sized computer, equipped with an ARM processor powerful enough to run most linux distributions. It should be for sale begin februari 2012, on the Rpi website.

Just got your new board, but you don't know where to begin? See the beginners guide.

The Foundation

The Raspberry Pi is a project by the Raspberry Pi Foundation which aims to bring computer interaction back to schoolkids, by producing very small, cheap computers.

System Specifications

The Rasberry Pi comes in two tastes, A and B, with B having more features. The General Purpose Input/Output (GPIO) pins on each board allow for the use of optional Rpi expansion boards

Software

main article: Rpi Software

The Raspberry Pi is a fully capable ARM computer, so it should be able to run about everything compiled in ARM.

Education

main article: Rpi Education

The Rpi is geared towards eduction. Here you should find teaching methods, hints and tips about how to use the Rpi in the classroom. A whole lot of good links can be found in Rpi Educational links.

Manual

Computing at School is writing a manual for the educational use of the Raspberry Pi.

Projects

main article: Rpi Projects

While the Rpi is intended for education, it is also the heart in many projects, from home automation to clustercomputers (called Rpi bramble in the jargon). Projects worked out here are useful as examples, inspiration or direct manual for your own projects, or those for more advanced pupils.

Accesoires

Expansion boards (shields)

main article: Rpi expansion boards

The Rpi GPIO pins on the board allow for the connection of many shields, adding more functions to the main board. These range from sensors (Rpi Gertboard) to connectivity (adding a VGA connection).

Screens

main article: Rpi Screens

Peripherals

main article: Rpi Peripherals

Most computer pheripherals will work with the Raspberry Pi without any problems.

Case

main article: Rpi cases

There is currently no official case for the Rpi. But due to it's small size and low power output it can be housed in about anything!
