Progressive Automations MegaMoto GT H-Bridge Arduino Shield LC-81

The LC-81 MegaMoto GT is a low-cost robust H-bridge "shield" for 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 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.
