Circuit Documentation

Summary

This circuit is designed to control two stepper motors using TB6600 and TB660 stepper motor drivers, and read inputs from a KY-023 Dual Axis Joystick Module. The ESP32 microcontroller is used to interface with these components. The circuit includes a 12V power supply and a Step Up Boost Power Converter to provide the necessary voltages.
