Credit-card sized computer Raspberry Pi has sold 2.5 million units around the world.
Created by the Raspberry Pi Foundation to encourage students to study computer programming by means of a cheap computer, the tech can cost as little as £20 to £30.
Following the latest milestone, the organisation has made financial donations to open source projects including XBMC, libav, PyPy, Pixman, Wayland/Weston, Squeak, Scratch and WebKit.
The Raspberry Pi Foundation said one of the next advancements for the computer would be to run an open source graphics driver successfully.
