WeMos D1 mini Lite


Platform Espressif 8266: Espressif Systems is a privately held fabless semiconductor company. They provide wireless communications and Wi-Fi chips which are widely used in mobile devices and the Internet of Things applications.

Microcontroller ESP8266
Frequency 80MHz
Flash 1MB
Vendor WEMOS


Please use d1_mini_lite ID for board option in “platformio.ini” (Project Configuration File):

platform = espressif8266
board = d1_mini_lite

You can override default WeMos D1 mini Lite settings per build environment using board_*** option, where *** is a JSON object path from board manifest d1_mini_lite.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = espressif8266
board = d1_mini_lite

; change microcontroller
board_build.mcu = esp8266

; change MCU frequency
board_build.f_cpu = 80000000L


WeMos D1 mini Lite supports the next uploading protocols:

  • espota
  • esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

platform = espressif8266
board = d1_mini_lite

upload_protocol = esptool


Debugging currently does not support WeMos D1 mini Lite board.
