User Guide

To help users quickly understand the various functions of the product, we provide a series of test routines for customers to learn how to use each interface. In addition to the ESP32-S3-CAM-OVxxxx main unit and its included cables, the following components are required to run the examples:

Component Preparation​

  • ESP32-S3-CAM-OVxxxx ×1
  • TF card ×1 (not required, needed only for TF card examples)
  • Screen, supports 1.83, 2inch, 2.8inch, 3.5inch ×1

Precautions​

  • When using, pay attention to the PCB antenna area. Avoid having other metal or plastic parts in contact with the PCB antenna.
  • The screen and camera occupy most of the GPIOs. The development board uses the CH32V003 chip as an I/O expander for control functions such as reset and backlight on/off.
  • The GH1.25 lithium battery connector supports only a single-cell 3.7 V lithium battery. Do not connect multiple battery packs simultaneously for charging or discharging. A single-cell capacity of 2000 mAh or less is recommended.
