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.
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.
