Is this design tested?

[happytm]

I was interested in using this design for four motors setup for moving four wheel platform. Before I buy these motor drivers to test it I wanted to confirm that the design is working. My motors are 24V DC.

Thanks.

Have you seen this? misan/dcservo#37 (comment). He is using 3 motors on STM32 Blue Pill.

Thanks.

Not thoroughly tested, but yes. I have put 1 motor on each of the 5 channels, and spun it exactly one rotation forwards then backwards. I have not done any testing with high load or anything like that, but all parts of the board are at least functional.

I suppose I should mention the resistor divider for the 5V regulator is wrong and causes the 5V rail to be extremely low voltage. It is easily fixed with a mod wire. I have yet to update the design files.

have you thought about using STM32 blue pill instead of 8 bit micro.

The ESP32 is the main controller and does all the work. I have an ATmega328 just as a PWM generator and nothing else. No 8 bit microcontrollers here.

Sure, the STM32 would probably work, but the ESP32 is nice because of its ability to be a webserver.
