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 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 seconds. not super fast.

What is EasyLoader?
1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed. .
  1. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click "Burn" to start burning. (For M5StickC burning, please Set the baud rate to 750000 or 115200)
