 The ESP32-CAM is a popular development board designed for applications requiring a camera module. It includes multiple data pins, a combined Wi-Fi and camera module, and a microSD card slot for easy storage. In this project we mainly use the Wi-Fi function and following pins: Power Pins (5V, 3.3V and GND), general purpose input/output pins (GPIO12), serial pins (U0R, U0T) and GPIO0.\\
 ====2.1.3 Adafruit Universal USB / DC / Solar Lithium Ion/Polymer charger - bq24074====
+The micro lipo charger is designed to charge Lithium Polymer or Lithium Ion (LiPoly/LiIon) batteries via a USB Type-C connection, DC or Solar power. This charger charges the batteries by plugging into a USB port and a 3.7V/4.2V LiPoly/LiIon to JST plug.\\
+The Micro-Lipo charger is charged in three stages. Firstly, pretreatment charging, then constant current fast charging, and finally constant voltage trickle charging. The charger has a 0.1-inch connector, D+ and D- data lines, 100mA charging current, which can be adjusted to 500mA by soldering off the jumper.
