Datasheet

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 half-
bridge 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.
Each half-bridge on the MegaMoto is independently controlled so stacking two or
three MegaMoto units allows an Arduino to drive three-phase brushless or stepper
motors as well as DC brushed motors. Not limited to motors, the MegaMoto 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.
