M5Stamp C3

The M5Stamp-C3 is a development board based on the Espressif ESP32-C3 a powerful chip that is used on many different board mostly because of the built-in radio that can be used for WiFi or Bluetooth wireless connections.

Flashing

CLI Flashing

In addition, you must install the esptool flashing tool:

https://github.com/espressif/esptool#easy-installation

Now you should be able to flash your board as follows:

  • Plug your ESP32-C3 board into your computer’s USB port.

  • Build and flash your TinyGo code using the tinygo flash command. This command flashes the ESP32-C3 with the serial example:

    tinygo flash -target=m5stack-core2 examples/serial
    
  • The ESP32-C3 board should restart and then begin running your program.
