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 ==
 
::''main article: [[Rpi 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 ==
 
 
 
[[File:Raspi-Model-AB-Mono-1-699x1024.png|300px|thumb|right|A diagram denoting the places of the different components on the Rpi]]
 
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.
 
 
 
== Accesoires ==
 
=== Add-on boards (shields) ===
 
::''main article: [[Rpi addOns]]''
 
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).
 
=== Peripherals ===
 
::''main article: [[Rpi Peripherals]]''
 
Most computer pheripherals will work with the Raspberry Pi without any problems.
 
 
 
== 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 ===
 
[http://www.computingatschool.org.uk/ 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.
