#REDIRECT [[R-Pi Hub]]
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 [http://www.raspberrypi.com Rpi website].

+
== 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 ==
+
::''main article: [[Rpi Hardware]]''
+
 
+
[[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.
+
 
+
== 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.
+
 
+
== 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!
