M5Stack
The m5stack is a development board based on the Espressif ESP32 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 on Linux
You need to install the Espressif toolchain for Linux to use TinyGo with the ESP32:
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 board into your computer’s USB port.
-
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the ESP32 with the serial example:tinygo flash -target=m5stack -port=/dev/ttyUSB0 examples/serial -
The ESP32 board should restart and then begin running your program.
CLI Flashing on macOS
You need to install the Espressif toolchain for macOS to use TinyGo with the ESP32:
https://docs.espressif.com/projects/esp-idf/en/release-v3.0/get-started/macos-setup.html
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 board into your computer’s USB port.
-
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the ESP32 with the serial example:tinygo flash -target=m5stack examples/serial -
The ESP32 board should restart and then begin running your program.
CLI Flashing on Windows
You need to install the Espressif toolchain for Windows to use TinyGo with the ESP32:
https://docs.espressif.com/projects/esp-idf/en/release-v3.0/get-started/windows-setup.html
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 board into your computer’s USB port.
-
Build and flash your TinyGo code using the
tinygo flashcommand. This command flashes the ESP32 with the serial example:tinygo flash -target=m5stack examples/serial -
