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.
