ESP32-CAM camera development board
Overview
ESP32-CAM is the latest small size camera module released by Essence. The module can work independently as the smallest system, with a size of only 27*40.5*4.5mm, and a deep sleep current as low as 6mA.
ESP32-CAM can be widely used in various IoT applications, suitable for home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, wireless positioning system signals and other IoT applications. It is an ideal solution for IoT applications .
ESP32-CAM adopts DIP package and can be used directly by plugging in the bottom plate, realizing the rapid production of products, providing customers with high-reliability connection methods, which is convenient for application in various IoT hardware terminal occasions.

Note
1. Please make sure that the input power of the module is at least 5V 2A, otherwise the picture may have water lines.
2. The ESP32 GPIO32 pin controls the camera power. When the camera is working, please pull GPIO32 low.
3. Since IO0 is connected to the camera XCLK, please leave IO0 in the air when using it, and do not connect it to high or low level.
4. The default firmware is already included in the factory, and no additional download is provided. Please be careful if you need to re-burn other firmware.
