    The Robot Power MegaMoto GT™ is a low-cost robust H-bridge "shield" for the Arduino™ and hardware compatible base units. The built-in cooling fan and heatsinks allow the MegaMoto GT to handle high current loads without overheating. Up to 50A (5 sec) of current may be controlled by the MegaMoto GT at 24V. This is over 1200W of power!

    The GT is ideal for Arduino users who want to control high current loads efficiently for robotics, scooters & Segways, industrial controls and many other applications by using their familiar development environment and without messy, unreliable "lash up" type connections to discrete motor controls.

    The MegaMoto GT is a dual half-bridge circuit that can be configured either has a full H-bridge or as two independent half-bridge circuits. This allows a single MegaMoto GT to drive one motor with full variable-speed control both forward and reverse. It also allows two independent motors to be controlled in a uni-directional fashion by connecting one side of each motor to the battery negative and the other motor lead to one of the MegaMoto GT outputs.

    Jumpers are used to select which Arduino signals drive the Enable and PWM inputs on each MegaMoto. This flexibility allows the MegaMoto GT to play nice with other shields which might require the use of certain pins.

    Not limited to motors, the MegaMoto GT can control other DC loads such as lights, solenoids, relays, valves, Peltier junction coolers, Hydrogen generators or basically any DC device within the operating voltage and current range.

    I rate the product 5 out of 5. I bought the product directly from manufacturer which gave excellent sales support.

    I used the board with an Arduino uno. The supplied software worked very well and provides bi-directional control of the motor at varying speeds.

    I like the sold contacts so the user does not have to worry about shorts when connecting the board to the battery and the motor.

    The board comes with colored leds which help in setting up the board.

    The board has a quiet on board fan. I recommend this product.
