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.

The Raspberry Pi is a fully capable ARM computer, so it should be able to run about everything compiled in ARM.
- 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.
Computing at School is writing a manual for the educational use of the Raspberry Pi.
- 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.

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