Announcing the achievement, the foundation wrote that one of its distributors – Element14 has sold over half a million units of the Raspberry Pi and even though the foundation doesn’t have up to date figures from its other distributor RS Components, it is expecting to have sold its millionth unit of the computer.

The foundation wrote on a blog post, “The folks at element 14/Premier Farnell announced today that they alone have now made and sold more than half a million Raspberry Pis.”

“They’re only one of two official distributors; we don’t have completely up-to-date figures from RS Components yet, but Farnell’s news suggests that we’re well on the way to having sold our millionth Raspberry Pi” the foundation added further.

After the order limit on the Raspberry Pi was lifted back in July last year, there has been a tremendous demand and increase in sales of the credit card sized computer. The Foundation continued its work in improvement of the board and in September last year came out with a revision 2.0 of the board.

Just about a week after the release of the new board, a team of researchers managed to build a cluster computer using the Raspberry Pi and Lego. With demand for higher processing power from enthusiasts, the Foundation released an official ‘Turbo Mode’ patch for the Pi the same month.

Further developments on Raspberry Pi included the availability of a camera module that could record 1080p videos, Minecraft pocket edition and the production of $25 variant of the Pi.
