ESP32CAM-PSRAM

SKU:U017-PCBA

Description

ESP32CAM-PSRAM is a development board for image recognition. It features an ESP32(4MB Flash + 520KB RAM + 4MB PSRAM) chip and 2-Megapixel camera (OV2640).

The module offers plenty of storage with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debugging through USB Type-C port.

The hardware comes with preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image resolution is 600*800, since it's 2MP camera, you sure can optimize the software to output a better resolution image.

Using processes:

  • 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.

Features

  • CP2104 USB-to-TTL converter
  • ESP32-WROVER (PCB Antenna)
  • WIFI image transmission
  • OV2640 Camera
  • Camera Field of View : 150 degree

Includes

  • 1 x ESP32CAM-PSRAM（Without Casing）

FAQ

Q: How does ESP32CAM-PSRAM use the original code of Le Xin esp32cam?

    1. Select development board M5TimerCAM
      2. Because the SIOD and VSYNC pins of ESP32CAM and ESP32CAM-PSRAM are different, the CAMERA type is selected 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 screen
