ESP32CAM is an image recognition development board that integrates the ESP32 (4M Flash + 520K RAM) chip and a 2-megapixel camera (OV2640). It supports WiFi image transmission and USB port debugging.
The hardware comes pre-installed with firmware, and development is done using ESP-IDF to run WiFi-camera applications. The default program outputs an image size of 600 x 800, but you can optimize the program to output larger sizes.
How is this program used?
Open your phone's Wi-Fi, scan, and connect to the AP hotspot starting with "m5stack-".
Open your phone's browser, visit 192.168.4.1, and enter the monitoring page to get real-time video.
The video frame rate is about 5-6 frames per second.
Since the module can generate a WiFi hotspot AP, you can use a phone, PC, or other devices to wirelessly obtain camera images via WiFi, or you can obtain camera images via the module's HY2.0-4P interface.

The PIN8 (PDWN) pin of the OV2640 chip is an enable pin, which is grounded through a 12KΩ pull-down resistor on this board to enable it and enter working mode. When the PIN8 (PDWN) pin is pulled high, it will enter Camera Power Down mode.
