Review on 💨 High-Power Adafruit DRV8871 DC Motor Driver Breakout Board - Up to 3.6A Max by Angela Banks

The quality of this product is to be expected from Adafruit. It was pretty easy to use and worked very well. I found that the PWM output was easily picked up by the mini audio amplifier that sat next to it on the breadboard. I removed the controller and that fixed the problem. I would suggest if you have an application like this you should use a shielded cable to connect the Arduino PWM pins to the motor controller.
