ESP32-CAM PSRAM
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.

FAQ
Q: How to use Espressif's original ESP32CAM code with ESP32CAM-PSRAM?
- Select the M5TimerCAM development board
2. Since the SIOD and VSYNC pin definitions differ between ESP32CAM and ESP32CAM-PSRAM, choose CAMERA MODEL M5STACK V2 PSRAM
3. Set the WiFi name and password
4. After uploading the program, connect to WiFi, enter 192.168.4.1 in the browser, and click start stream to see the video.
- Select the M5TimerCAM development board
