The credit card-sized Raspberry Pi was designed as a low-cost, portable board that kids could plug in and start coding wherever they were.
By making it simple for children to program, the foundation hoped to inspire the next generation of programmers, similar to how many of today’s UK developers cut their teeth on the BBC Micro. With the two million boards sold the Pi has now outsold the computer that inspired its creation, as just over 1.5 million BBC Micros are estimated to have been sold.
