C3Pi, the tracked robot that I've been working on for several years, just got a new brain: a Raspberry Pi model B+.
The old version used a Model B with an Arduino micro. This one will probably use a Teensy 3.0 as the Pi's companion.
(Less) Power to the Raspberry PiThe main reason for upgrading the Pi is the reduced power consumption, but the extra mounting holes also appealed.
I took the opportunity of replacing C3Pi's old stripboard top with a proper pololu board, and the result looks much neater.
I've added the motor controller which also provides a regulated 5v supply. My next job is to make a small circuit board to hold the Teensy and provide connection points to the Pi and the controller.
