In 2006, early concepts of the Raspberry Pi were based on the [[Atmel]] [[ATmega|ATmega644]] microcontroller. Its schematics and PCB layout are available for public download.<ref name="ubergizmo build your own">{{cite web | url=http://www.ubergizmo.com/2011/10/build-raspberry-pi-minicomputer/ | title=Build your own prototype Raspberry Pi minicomputer | publisher=ubergizmo | date=October 24, 2011 | accessdate=November 02, 2011 | author=Wong, George}}</ref> Trustee Eben Upton assembled a group of teachers, academics and computer enthusiasts to devise a computer to inspire children.<ref name="guardian reboot computing">{{cite news | url=http://www.guardian.co.uk/education/2012/jan/09/raspberry-pi-computer-revolutionise-computing-schools?newsfeed=true | title=Raspberry Pi device will 'reboot computing in schools' | work=[[The Guardian]] | date=January 09, 2012 | accessdate=January 20, 2012 | author=Moorhead, Joanna}}</ref>

In October 2011, the logo was selected from a number submitted by members of the community. A shortlist of six was drawn up, with the final judging taking several days. The chosen design was based on a [[buckyball]].<ref name="geek.com very clever logo">{{cite web | url=http://www.geek.com/articles/chips/raspberry-pi-selects-a-very-clever-logo-20111010/ | title=Raspberry Pi selects a very clever logo | publisher=geek.com | accessdate=October 11, 2011 | author=Humphries, Matthew}}</ref> During the same month, a development version of {{nowraplinks|[[RISC OS{{!}}RISC OS 5]]}} was being worked on<ref name="iconbar newsround">{{cite web | url=http://www.iconbar.com/articles/Newsround/index1271.html | title=Newsround | work=[[The Icon Bar]] | accessdate=October 17, 2011 | author=Lee, Jeffrey}}</ref> and demonstrated in public.<ref name="osnews risc os">{{cite web | url=http://www.osnews.com/story/25276/Raspberry_Pi_To_Embrace_RISC_OS | title=Raspberry Pi To Embrace RISC OS | work=[[OSNews]] | date=October 31, 2011 | accessdate=November 01, 2011 | author=Holwerda, Thom}}</ref><ref name="archive london show 2011">{{cite news | title=The London show 2011 | work=Archive (magazine) | date=December 2011 | accessdate=January 19, 2012 | author=Dewhurst, Christopher | volume=23 | issue=3 | pages=3}}</ref>
