Arduino Compatible Mega Motor Shield 1A, 5-28V

The Robot Power MegaMoto

is a low-cost robust H-bridge "shield" for the

Arduino

and hardware compatible base units. The standardized shield format

stacking headers allows multiple MegaMoto units to be controlled by a single

Arduino Uno or Duemilanove using pass-through stacking headers.

The MegaMoto is the first and only motor control for Arduino that gives users the

ability to control up to 30A of current at up to 28V. That's over 800W 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 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 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 outputs.

The true flexibility of the MegaMoto 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 to play nice with other shields which might require the use of certain

pins.

Since the Uno and Duemilanove have six hardware PWM outputs, up to three MegaMoto units may be stacked on a single Arduino base unit. This allows forward and reverse control of up to three motors or up to six motors in halfbridge mode. Arduino Mega and some units based on other CPU chips have more PWM outputs available and thus may be able to control even more MegaMotos.
