Circuit Documentation

Summary

This document provides a detailed overview of a circuit that integrates an ESP32 Devkit V1 microcontroller, a LoRa Ra-02 SX1278 module, a motor driver (ponte h), two motors with reducers, a 12V power supply, an AC source, and a rocker switch. The ESP32 Devkit V1 is used to control the LoRa module and the motor driver, which in turn controls the motors. The power supply provides the necessary voltage to the components, and the rocker switch is used to control the power to the motor driver.
