The motor controller came in kit form from Active Robots and had to be soldered together. It is based around the 298 controller chip. The completed module can be used with a supply voltage of up to 26volts, and includes a voltage regulator to provide a regulated 5volt output for any control circuitry. I am using this 5volt output to feed the Arduino temporarily because I have misplaced one of the battery pack flying leads.
Components included in the kit.
