Circuit Documentation

Summary

The circuit in question appears to be designed for controlling multiple servo motors using an ESP32 microcontroller. The ESP32 is powered by a breadboard power module that can supply both 3.3V and 5V, which is in turn powered by a 9V battery through a toggle switch and a barrel jack with a terminal block. The servos are powered by the 5V output from the breadboard power module and are controlled by specific GPIO pins on the ESP32.
