Description

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 192.168.4.1
  • 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.

  • 9-axis gyroscope (MPU6050)
  • pressure sensor (BME280)
  • Analog MIC (SPQ2410)
  • Lipo Battery power pins

Please notice: There are 2 types of M5Camera

  • Model A & Model B
  • They have different circuits, can be identified by backside sticker
  • Model A is halt production. The new coming M5Camera is just Model B
  • In Model A circult design MPU6050 and camera sensor have I2C conflict, which means you can’t use both at the same time.
  • Model B have better performance on image quality and processing speed.
