Hi All,
Wanted to let you know about my company's new motor control shield for Arduino - the MegaMoto. This is a 7V-28V, 13A continuous, 30A+ peak stacking shield. It contains two half-bridge MOSFET chips so it can control one motor in H-bridge (forward/reverse) mode or two in half-bridge (forward only) mode.
Jumpers connect the MOSFET inputs to the Arduino output pins so you can choose which pins control the Enable and PWM inputs. Since the Uno has 6 PWM outputs you can stack 3 of the MegaMotos on one Arduino. Also since the MOSFETs are independent half-bridge chips you can control brushless and stepper motors as well.
