Use this motor driver and power distribution board to get your Romi chassis running quickly. It offers all of the same features as the smaller Power Distribution board for Romi Chassis — battery contact slots, reverse voltage protection, several power switching options, and easy access to the various power busses — and adds a two-channel motor driver and powerful switching step-down regulator that can supply a continuous 2.5 A at 5 V or 3.3 V. Just add a microcontroller and sensors to complete your Romi robot.
