The Raspberry Pi was first introduced in early 2012 as a simple, low cost, computer fit onto a circuit board roughly the size of a credit card. The idea was to use this low cost computer to promote teaching of computer science in schools but it has grown to be so much more! Since its release, well over 30 million of these little computers have been sold. We have carried the Raspberry Pi in Canada since it first became available and have watched as the Pi has morphed into a complete development platform with powerful single-board computers, cameras, touchscreens, and other accessories. Its multitude of inputs and outputs for electronics and computer peripherals and its impressive computing power mean it can be used to make just about anything you can imagine. The newest and most powerful version, the Raspberry Pi 4, is now available!
