ESP32CAM is an image recognition development board. It features an ESP32 (4M Flash + 520K RAM) chip and 2-Megapixel camera (OV2640). It also supports image transmission via Wi-Fi and debugging through USB Type-C port.
The hardware comes with a preloaded software, programmed by ESP-IDF. The purpose of the pre-loaded software is to operate the Wi-Fi camera. The camera output image has a resolution of 600*800, since it's 2MP camera it's possible to optimize the software to output a bigger resolution of photos.
What can the software do?
- 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 seconds. not super fast.

ESP32 Camera Module Development Board (OV2640)
The module comes with a self-contained program. It is a nice program to demonstrate the camera. However, 1) I think the "can" program was developed with ESP-IDF not Arduino. 2) there is no instruction to change the SSID of the module.
A simple sketch for the Arduino environment at the product page would be nice.
in the product document page, we have provided Arduino example for the camera
It worked well. Picture quality good.
Device works as advertised.
