    Description

    ESP32-CAM is an ESP32 Wireless IoT Vision Development Board in a tiny form factor, designed to be used in various IoT projects, such as home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, and so on. It supports deep sleep mode with power consumption as low as 6mA at 5V, making it ideal for portable IoT applications. It's suitable as a low-cost CCTV camera.

     

    Check out this easy setup to use the ESP32-CAM by Easy One:

     

     

    ESP32-CAM module comes with two rows of male header pins soldered. Prototyping and testing can be carried out right away.

    Minimal Functional Circuit

    • Always power up the board with at least a 5V 2A power supply to eliminate horizontal colored lines across the camera image. Please make sure that the 5V power source is able to maintain 5V output when the ESP32-CAM module is streaming.
    • DO NOT pull the IO0 (Input Output Zero) pin to logic HIGH or LOW during normal operation.

     

     

    Note:: From June 2025 onwards, the ESP32 Camera board comes with the RHYX M21-45 camera, similar to the OV7670 (previously it came with the OV2460 camera). The OV7670 provides VGA resolution with PIXFORMAT_RGB565,

    You would not have problems with live streaming images or videos. However, the ESP32 Camera board can only save the images in raw RGB565 format and you can compress the image to BMP format. Please refer to this tutorial to learn more.

    Note: From 12th of August 2025 onwards, the ESP32 Camera board comes with the OV2460 image sensor. The previous version comes with RHYX M21-45 image sensor (similar to the OV7670).
