Tiny Raspberry Pi A+ SBC goes for $20
The Raspberry Pi Foundation launched a Model A+ with a $20 price, a tiny 65 x 56mm, 23g footprint, and a 40-pin array, making it a better fit for robotics. Despite its lower, $25 price, the Raspberry Pi Model A has never come close to the popularity of its larger, more feature rich sibling, the Model B. This summer, the B was upgraded to the Model B+, which kept the Model B’s $35 price, while adding several new features, some of which have been passed on to the now $20 Model A+.
