M5Stack ESP32 Fisheye Camera Module with PSRAM (OV2640)


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.
