Configuration

Please use esp_wroom_02 ID for board option in “platformio.ini” (Project Configuration File):

[env:esp_wroom_02]
platform = espressif8266
board = esp_wroom_02

You can override default ESP-WROOM-02 settings per build environment using board_*** option, where *** is a JSON object path from board manifest esp_wroom_02.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:esp_wroom_02]
platform = espressif8266
board = esp_wroom_02

; change microcontroller
board_build.mcu = esp8266

; change MCU frequency
board_build.f_cpu = 80000000L

Debugging

PIO Unified Debugger currently does not support ESP-WROOM-02 board.
