Among these are the Serial Servo Raspberry Pi HAT, the Serial Servo based on ESP32, the Serial Servo Pico HAT, the Serial Servo Arduino Shield, and the Serial Servo Breakout.

An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.

This shield could be a good alternative to hobby RC controllers for robots that need a customizable open-source motor controller. The PCB design and source code are available on GitHub.
