The Raspberry Pi computer is now available for order for just £22 (about $35). A cheaper £16 ($25) version will go on sale later in the year.

About the size of a credit card, t has a processor, memory chip, Ethernet port to connect to the Internet, and a couple of USB ports to plug a keyboard and mouse.

The Raspberry Pi Foundation is talking to exam boards and educational publishers about incorporating the Pi into British lesson plans.

“This is about getting kids to engage creatively with computers: doing interesting things,” says the Foundation’s Eben Upton. “And to be fair that doesn’t even have to be programming: it can be art, it can be design, using computers in a creative way.”
