WeMos D1 MINI ESP32¶

Hardware¶

Platform Espressif 32: 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 wemos_d1_mini32 ID for board option in “platformio.ini” (Project Configuration File):

[env:wemos_d1_mini32]
platform = espressif32
board = wemos_d1_mini32

You can override default WeMos D1 MINI ESP32 settings per build environment using board_*** option, where *** is a JSON object path from board manifest wemos_d1_mini32.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:wemos_d1_mini32]
platform = espressif32
board = wemos_d1_mini32

; change microcontroller
board_build.mcu = esp32

; change MCU frequency
board_build.f_cpu = 240000000L

Uploading¶

WeMos D1 MINI ESP32 supports the next uploading protocols:

• esp-prog

• espota

• esptool

• iot-bus-jtag

• jlink

• minimodule

• olimex-arm-usb-ocd

• olimex-arm-usb-ocd-h

• olimex-arm-usb-tiny-h

• olimex-jtag-tiny

• tumpa

Default protocol is esptool

You can change upload protocol using upload_protocol option:

[env:wemos_d1_mini32]
platform = espressif32
board = wemos_d1_mini32

upload_protocol = esptool

Debugging¶

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

WeMos D1 MINI ESP32 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
