Learn
The hardware comes pre-installed with firmware, and you can develop using ESP-IDF to run the WiFi-camera application. The default program outputs images at a resolution of 600 x 800, but you can optimize the program to output larger sizes.
How to use this program?
- Turn on your phone's Wi-Fi, scan and connect to the AP hotspot named "m5stack-".
- Open your phone's browser and visit 192.168.4.1 to access the monitoring page and get real-time video.
- The video frame rate is approximately 5-6 frames per second.

The PIN8 (PDWN) of the OV2640 chip is the enable pin. In this board, it is enabled by a 12KΩ pull-down resistor to ground, entering the working mode. When PIN8 (PDWN) is pulled high, it will enter Camera Power Down mode.
