Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an ESP32 CAM module, an FTDI Programmer, a Stepdown 18V to 5V converter, a Micro USB to Cable (2 Pin), and a 12V Battery (mini). The circuit is designed to power the ESP32 CAM module and facilitate communication with a computer via the FTDI Programmer. The Stepdown converter is used to step down the voltage from the 12V battery to 5V, which is then supplied to the ESP32 CAM and FTDI Programmer.
