NEW PRODUCT: MegaMoto Robot Shield for Arduino: control high power, high current motors with Arduino today! The Robot Power MegaMoto PlusTM is a low-cost robust H-bridge “shield” for the ArduinoTM and hardware compatible base units. The standardized shield format stacking headers allows multiple MegaMoto Plus units to be controlled by a single Arduino Uno or Duemilanove using pass-through stacking headers. The MegaMoto Plus is the first and only Robot Shield for Arduino that gives users the ability to control up to 40A of current at up to 28V. That’s over 1100W of power! At last Arduino users can easily control high-current, high-power motors 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 Plus is a dual half-bridge circuit that can be configured either as a full H-bridge or as two independent half-bridge circuits. This allows a single MegaMoto Plus 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 Plus outputs. The true flexibility of the MegaMoto Plus is shown when multiple units are stacked onto a single base Arduino unit. Jumpers are used to select which Arduino signals drive the Enable and PWM inputs on each MegaMoto. This flexibility allows the MegaMoto Plus to play nice with other shields which might require the use of certain pins. Most recently, Megamoto Plus was used in the MIT project to help product more emergency ventilators for the COVIS crisis. You can see the details here:
