Pololu dual motor controller + Tamiya 70168
July 13, 2008
I bought a Tamiya 70168 twin gearbox and Tamiya wheels and hooked them up to my Pololu micro dual serial motor controller. They don't even budge. I hooked up GM-10 motors and they work as they should. I changed motor power to 9v instead of 6v, motor 0 turned for a second and stopped. Again the GM-10 motors ran fine. If I apply power direct to Tamiya from battery, either 6v (4 @ AA) or 9v (9v cell), it turns as you would expect. All of this was done with no load on Tamiya, the wheels were not even touching the ground. I used freshly charged batteries.
Any ideas? I'm stumped. Would a 0.1 uF capacitor across the motor leads help?
