PSRAM Camera Module (OV2640)


Regular price $13.39
Standard Shipping Estimated Delivery Time: 7-20 days

M5CameraX is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel carmera(OV2640).M5Camera offers plenty of storage, with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debuging through USB Type-C port.

The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it’s 2-Maga camera, you sure can optimize the software to output the maximum size of photos.

what this software can do?

  • 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
  • Then here comes the picture. Video is about 5-6 frames per senconds. not super fast.

The hardware also comes with some reserved weld pad, just in case you want put these chips back on board.
