Circuit Documentation

Summary

This circuit is designed to control two TB6600 stepper motor drivers using an Arduino Nano and a KY-023 Dual Axis Joystick Module. The joystick controls the direction and speed of the stepper motors. The circuit is powered by a 12V power supply, and a DC-DC converter is used to step down the voltage for the Arduino Nano and other components.
