Hardware¶

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.

Configuration¶

Please use d1_mini ID for board option in “platformio.ini” (Project Configuration File):

[env:d1_mini]
platform = espressif8266
board = d1_mini

You can override default WeMos D1 R2 and mini settings per build environment using board_*** option, where *** is a JSON object path from board manifest d1_mini.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:d1_mini]
platform = espressif8266
board = d1_mini

; change microcontroller
board_build.mcu = esp8266

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading¶

WeMos D1 R2 and mini supports the following uploading protocols:

• espota

• esptool

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:d1_mini]
platform = espressif8266
board = d1_mini

upload_protocol = esptool

Debugging¶

Debugging currently does not support WeMos D1 R2 and mini board.
