I made the v1.0 motor controller last week.
In the v1.0 pcb works. I used A4950 as the motor driver and as5600 as the encoder of my DC-motor.
Oh, by the way, the DC-motor I used is WS-50ZYT78-R which I used in my last project Open-Source inverted pendulum
It's a powerfull motor. Its peak troque current is more than 10A. Unfortunately A4950's power is so weak that can not drive this motor in its max torque.
So I have to find a more powerfull motor driver for this application. After seeking, I finally find a motor driver chip which seem is exactly what I need. The chip model is VNH5180A.
VNH5180A is a motor driver chip used in automotive application. Its max output current is 8A. Even thought as powerfull as this motor driver is, I still not 100% sure that it's good enought for me. I need to make a prototype to test my new driver.
Here is my v2.0 Motor contorller PCB.
