The '''Raspberry Pi''' is a credit-card-sized [[single-board computer]] developed in the [[United Kingdom|UK]] by the [[Raspberry Pi Foundation]] with the intention of promoting the teaching of basic [[computer science]] in schools.<ref name=cheatsheet>{{cite web|url=http://www.silicon.com/technology/hardware/2011/10/03/raspberry-pi-cheat-sheet-39748024/ |title=Raspberry Pi: Cheat Sheet |publisher= Silicon.com |accessdate=6 May 2012}}</ref><ref name="faq">{{cite web | title = FAQs | publisher = Raspberry Pi Foundation | url = http://www.raspberrypi.org/?page_id=8 | accessdate =6 October 2011}}</ref><ref>{{cite web | last = Cellan-Jones | first = Rory | authorlink = Rory Cellan-Jones | title = A £15 computer to inspire young programmers |publisher=BBC News | date = 5 May 2011 | url = http://www.bbc.co.uk/blogs/thereporters/rorycellanjones/2011/05/a_15_computer_to_inspire_young.html }}</ref><ref>{{Cite news | last = Price | first = Peter | title = Can a £15 computer solve the programming gap? | publisher = [[Click (TV programme)|BBC Click]] | date = 3 June 2011 | url = http://news.bbc.co.uk/2/hi/programmes/click_online/9504208.stm | accessdate =2 July 2011}}</ref><ref>{{cite web | url = http://www.electronicsweekly.com/Articles/2011/05/25/51129/Dongle-computer-lets-kids-discover-programming-on-a.htm | title = Dongle computer lets kids discover programming on a TV | accessdate =11 July 2011 | last = Bush | first = Steve | date = 25 May 2011 | publisher = [[Electronics Weekly]]}}</ref>

The Raspberry Pi is manufactured through licensed manufacturing deals with [[Element 14 (company)|Element 14]]/[[Premier Farnell]] and, [[RS Components]] and Egoman. BothAll of these companies sell the Raspberry Pi online.<ref>[http://www.raspberrypi.org/about about the Licensed manufacturing deal]</ref>

Egoman produce a version that is only able to be distributed in China and Taiwan and can be distinguished from other Pis as they are Red and do not have the FCC/CE marks. All of the hardware is the same.

The Raspberry Pi has a [[Broadcom]] BCM2835 [[system on a chip]] (SoC),<ref name="Broadcom-BCM2835-Website"/> which includes an [[ARM11|ARM1176JZF-S]] {{nowrap|700 MHz}} processor (The firmware includes a number of "Turbo" modes so that the user can attempt overclocking, up to 1&nbsp;GHz, without affecting the warranty),<ref name="Turbo mode">{{cite web|title=Introducing turbo mode: up to 50% more performance for free|url=http://www.raspberrypi.org/archives/2008|publisher=Raspberrypi.org|accessdate=20 September 2012}}</ref> [[VideoCore]] IV GPU,<ref name="grandmax brose 2012">{{cite news | url=http://www.grandmax.net/2012/01/broadcom-bcm2835-soc-has-powerful.html | title=Broadcom BCM2835 SoC has the most powerful mobile GPU in the world? | work=Grand MAX | date=30 January 2012 | accessdate=13 April 2012 | author=Brose, Moses}}</ref> and was originally shipped with 256 megabytes of [[Random-access memory|RAM]], later upgraded to 512MB.<ref name=512MB>{{cite web|url=http://www.raspberrypi.org/archives/2180 |title=Model B now ships with 512MB of RAM |publisher=Raspberrypi.org |date= |accessdate=2012-10-15}}</ref> It does not include a built-in [[hard disk drive|hard disk]] or [[solid-state drive]], but uses an [[Secure Digital|SD card]] for booting and long-term storage.<ref name="VerifiedPeripheralList"/> The Foundation's goal is to offer two versions, priced at US$25 and US$35. The Foundation started accepting orders for the higher priced model B on 29 February 2012,<ref name= lawler>Richard Lawler, 29 February 2012, [http://www.engadget.com/2012/02/29/raspberry-pi-credit-card-sized-linux-pcs-are-on-sale-now-25-mo/ Raspberry Pi credit-card sized Linux PCs are on sale now, $25 Model A gets a RAM bump], Engadget</ref> and the lower cost model A on 4 February 2013.<ref>[http://www.raspberrypi.org/archives/3215 launch of the model A announced]</ref>
