Circuit Documentation
Summary of the Circuit
This circuit integrates an ESP32 CAM module with a TF LUNA LIDAR sensor, powered by a Polymer Lithium Ion Battery through a Step Up Boost Converter. The ESP32 CAM module serves as the central processing unit, capable of handling image processing and communication tasks, while the TF LUNA LIDAR provides distance measurement capabilities. The Step Up Boost Converter elevates the battery's voltage to a level suitable for powering the ESP32 CAM. The battery provides a portable power source for the entire system.
