Learn to program, control robots or just stream music using this tiny computer.
The Raspberry Pi Model B+ is, like previous models, a tiny computer built for hobbyists, students and anyone who wants to learn more about how computers and computer programs work.
Comparing to its predecessor – the model B , the B+ has a microSD slot (instead of a full-size SD version) and a combined audio/video port (instead of separate stereo sound and composite video connectors). These changes were necessary to make room for its 40-pin GPIO (General Purpose Input/Output) connector that’s designed to connect and control other devices. You can still connect equipment designed for the B’s 26-pin connector, but the extra pins let you hook up even more sensors, lights and motors. It also has four (up from two) USB ports.
