ESP32-CAM PSRAM
SKU:U017-PCBA
Description
ESP32CAM-PSRAM is a fisheye wide-angle image recognition development board with a field of view of 150°, integrating an ESP32 (4MB Flash + 520KB RAM + 4MB PSRAM) chip and a 2-megapixel camera (OV2640). It supports WiFi image transmission and USB port debugging.
The hardware comes pre-installed with firmware, and you can develop programs 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.
Usage process:
- Turn on your phone's Wi-Fi, scan and connect to the AP hotspot starting with "m5stack-".
- Open the browser on your phone and visit 192.168.4.1 to enter the monitoring page and get real-time video.
- The video frame rate is approximately 5-6 frames per second.
Since the development board 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 wired HY2.0-4P interface on the development board.

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