Circuit Documentation

Summary

This document provides a detailed overview of a circuit involving an ESP32 microcontroller, two NEMA23 stepper motors, two DM542 stepper drivers, and a 24V DC power supply. The ESP32 controls the stepper drivers, which in turn drive the NEMA23 stepper motors. The power supply provides the necessary voltage for the stepper drivers.
