I need to control two 80RPM 12 VDC motors. My budget is reduced so I want to use things that I have to control it. Now I have a Pololu dual motor controller which drive 1A per motor at 12VDC. I was thinking about using this controller as a PWM driver to drive a H-Bridge (if I can build it is better).
Does anyone have some good plans of an H-bridge to drive about 3A or maybe more?
Is it possible to do what I'm thinking?
