Raspberry Pi Model A+ Developer Board
Raspberry Pi Model A+ Developer Board overview
Raspberry Pi Model A+ is a smaller, low-cost version of the Raspberry Pi. It is based on the BCM2835 system-on-chip (SoC), which includes an ARM11 processor and a powerful GPU. The Raspberry Pi Model A+ is recommended more for embedded and low-power projects that do not require Ethernet or multiple USB port
The Raspberry Pi model A+ features lower power consumption, better audio performance and a 40-pin GPIO connector in an even smaller package. With its 0.1″-spaced GPIO header and small size, the pi model A+ also works as a programmable controller in a wide variety of robotics and electronics applications.
