• Documentation (advanced usage, packages, boards, frameworks, etc.)

Requirements

1. Install PlatformIO
2. Create PlatformIO project and configure a platform option in platformio.ini file:

Tasmota release Arduino 3.1.3.250504 and IDF 5.3.3.250501

Support for the ESP32/ESP32solo1, ESP32C2, ESP32C3, ESP32C6, ESP32S2, ESP32S3 and ESP32-H2

[platformio]
platform = https://github.com/tasmota/platform-espressif32/releases/download/2025.05.30/platform-espressif32.zip
framework = arduino

Hybrid compile: Build customized Arduino IDF libraries

Adding the new option custom_sdkconfig in an [env] will compile the Arduino libraries using the sdkconfig settings from the framework and adds the changes specified in custom_sdkconfig. After the compile run the Arduino project [env] is compiled with the customized libraries.

Example: Switching off PPP modem support only for [env:esp32-no-PPP]

[env:esp32-no-PPP]
board = esp32dev
custom_sdkconfig = '# CONFIG_LWIP_PPP_SUPPORT is not set'

ESP32 Arduino

[env:esp32]
board = esp32dev

ESP32 Solo1 Arduino

[env:esp32solo1]
board = esp32-solo1

The released frameworks can be downloaded here
