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.

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

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.


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