Espressif Systems is a privately held, fabless semiconductor company renowned for delivering cost-effective wireless communication microcontrollers. Their innovative solutions are widely adopted in mobile devices and Internet of Things (IoT) applications around the globe.

Usage

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

Tasmota release Arduino 3.1.3.250712 and IDF 5.3.3.250702

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

[platformio]
platform = https://github.com/tasmota/platform-espressif32/releases/download/2025.07.31/platform-espressif32.zip
framework = arduino

Hybrid compile: Build customized Arduino IDF libraries

Adding the 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'

[env:esp32solo1]
board = esp32-solo1
