Arduino core for the ESP32 family of SoCs
Our Development is fully tracked on this public Roadmap 🎉
For even more information you can join our Monthly Community Meetings 🔔.
You can use the Arduino-ESP32 Online Documentation to get all information about this project.
Migration guide from version 2.x to 3.x is available here.
APIs compatibility with ESP8266 and Arduino-CORE (Arduino.cc) is explained here.
Here are the ESP32 series supported by the Arduino-ESP32 project:
SoC Stable Development Datasheet ESP32 Yes Yes ESP32 ESP32-C3 Yes Yes ESP32-C3 ESP32-C5 Yes Yes ESP32-C5 ESP32-C6 Yes Yes ESP32-C6 ESP32-H2 Yes Yes ESP32-H2 ESP32-P4 Yes Yes ESP32-P4 ESP32-S2 Yes Yes ESP32-S2 ESP32-S3 Yes Yes ESP32-S3[!NOTE] ESP32-C2 and ESP32-C61 are also supported by Arduino-ESP32 but require using Arduino as an ESP-IDF component or rebuilding the static libraries. For more information, see the Arduino as an ESP-IDF component documentation or the Lib Builder documentation, respectively.
For more details visit the supported chips documentation page.
You can use EspExceptionDecoder to get meaningful call trace.
Before reporting an issue, make sure you've searched for similar one that was already created. Also make sure to go through all the issues labeled as Type: For reference.
Finally, if you are sure no one else had the issue, follow the Issue template or Feature request template while reporting any new Issue.
We have set-up CI testing for external libraries for ESP32 Arduino core. You can check test results in the file LIBRARIES_TEST. For more information and how to add your library to the test see external library testing in the documentation.
We welcome contributions to the Arduino ESP32 project!
See contributing in the documentation for more information on how to contribute to the project.
We would like to have this repository in a polite and friendly atmosphere, so please be kind and respectful to others. For more details, look at Code of Conduct.
