DC motor driver board – Circuit Playground show-and-tell

My Project-1

Paul sent in his latest project via the Circuit Playground show-and-tell feature! He writes -

Hi Adafruit! Here’s something I made that I wanted to share… Dc motor driver board . Relays, mosfets and transistors. Powers two motors. The relay flips the positive and negative leads to the motor. The transistor drives the relay coil, and the MOSFET provides on/off and pwm speed control.

  1. Oh man, that would have come in handy last weekend when working on our submarine for the Red Bull Creation Challenge. Nice clean design there!
