mbed 3pi Robot Expansion Board

An addon PCB for using the mbed microcontroller to control Pololu's 3pi robot. This was built for a university project to add position and orientation sensors to the 3pi robot.

Chris from mbed has kindly taken my rough eagle schematic and built an Eagle library from it - available for download here. mbed and Pololu have since collaborated to build the m3pi - an addon board with prototyping space, a mbed socket, USB host, XBee and more.
