Thanks for your response. Where does it say that in the datasheet? I believe you, I just can't find it in there.. I bought a bunch of 1A schottky diodes on ebay, will those work as well as the MUR1560 you mentioned? Do you put the filter cap (.1uF?) on the motor itself or on the pcb where the motor wires connect? Also, do you think it would be a bad idea to power the motors and microcontroller from the same power supply (batteries)?
