I've recently been successful with this motor controller. Its inexpensive and very easy to drive; http://www.dfrobot.com/index.php?route=product/product&product_id=66
There's just a PWM speed pin and a 0/5V direction pin for each motor. The board can draw its logic power from the same hookup as the motor battery power. So its dead easy to wire up. The controller and the IOIO can both be powered directly from the battery pack and there are only 4 control pins, but I did have to put pullup resistors on all the pins. -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
