Description
ESP32CAM is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel camera(OV2640). It also supports image transmission via Wi-Fi and debuging through USB Type-C port.
The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it's 2-Maga camera, you sure can optimize the software to output the maximum size of photos.
To see what this software can do? Please flow the steps.
- Power the board via USB type-C or GROVE
- Use your phone to Wi-Fi scan an AP name start with 'm5stack-' and click to connect this AP. Open up web browser on your phone and visit 192.168.4.1
- Then here comes the picture. Video is about 5-6 frames per senconds. not super fast.
The hardware also comes with some reserved weld pad, just in case you want put these chips back on board.
- USB type-C or GROVE power input
- 6-axis gyroscope (MPU6050)
- pressure sensor (BMP280)
- analog MIC (SPQ2410)
- Battery socket
ESP32CAM is the most popular pattern among the M5 camera series so far. If you need more storage please check M5Camera. If you need fisheye lens, please check M5CameraF.

NOTE:
-
Camera Power Down pin is connected to ground via 12k ohm on board.
-
does not need to be connected to ESP32 GPIO. Instead it may be pulled down to ground with 10 kOhm resistor.
-
We have several patterns of camera board, the following figures shows the main difference
