A Raspberry Pi is a credit card-sized computer originally designed for education, inspired by the 1981 BBC Micro. Creator Eben Upton's goal was to create a low-cost device that would improve programming skills and hardware understanding at the pre-university level. But thanks to its small size and accessible price, it was quickly used for all sorts of great projects and collaborations and has been used in schools, living rooms, nature reserves, outer space and even the oceans. 

The Raspberry Pi is British built low cost computer, slower than a modern laptop or desktop but capable of running a full operating system that enables everybody to learn computing.
