Description

NOTE:

To use the 2640 camera, the following code needs to be modified: comment the 71 line code, open the 72 line code, and change the JPEG format to RGB565 format to use it normally.

Features:
1. This module is a small-sized camera module that can function independently as the smallest system.
2. A brand new WiFi+BT dual-mode development board designed based on ESP32, with onboard PCB antenna.
3. ESP32-CAM is an 802.11b/g/n Wi Fi+BT/BLE SoC module with ultra-low power consumption and deep sleep current as low as 6mA, making it suitable for IoT applications with high power requirements..
4. Easy to use, ESP32-CAM is a micro module with camera function, equipped with OV2640 camera, GPIO for connecting peripherals, and a micro-SD card for storing captured images. It can be used directly by plugging it into the motherboard.
5. ESP32-CAM can be widely used in various IoT scenarios, suitable for home smart devices, industrial wireless control, wireless positioning system signals, and other IoT applications. It is an ideal solution for IoT applications.
