The Raspberry Pi computer is just a small green circuit board about the size of a credit card – but it is hoped that it will get thousands of schoolchildren interested in programming. Created by a group of scientists and developers who wanted to improve the state of Britain’s computer science curriculum, the device contains a processor similar to the one used in many smart phones, a memory chip, an Ethernet port to connect to the internet and a couple of USB ports.
