DC brushed motor driver IC version (verified)

Overview

Use XT30 interface for power supply, use LM2596 to stabilize 5V, and use AMS1117 to stabilize 3.3V.

Four-channel DC brush motor driver, either AT8870 or A4950 can be used.

Using a 0.1R sampling resistor, the single-channel driver current limit is 3.3A.

The test input is 16.8V, and the theory supports 7.4V-24V input.
