GertBot Robotics Board for the Raspberry Pi 3 or Raspberry Pi 2

Quick Overview

The Gertbot is a motor/power controller board for the Raspberry-Pi. The strength of the board is that it has its own CPU which frees up the Raspberry-Pi from a lot of intense computations and will take care of all the real time requirements. All you have to do is give it high level commands. Like: Board 2, Motor 1, take 2432 steps at 67 Hz. Even giving those commands is done for you using the free GUI which comes with it!
