### Supported Chips

Here are the ESP32 series supported by the Arduino-ESP32 project:

| **SoC**  | **Stable** | **Development** |                                           **Datasheet**                                           |
|----------|:----------:|:---------------:|:-------------------------------------------------------------------------------------------------:|
| ESP32    |     Yes    |       Yes       |    [ESP32](https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf)    |
| ESP32-S2 |     Yes    |       Yes       | [ESP32-S2](https://www.espressif.com/sites/default/files/documentation/esp32-s2_datasheet_en.pdf) |
| ESP32-C3 |     Yes    |       Yes       | [ESP32-C3](https://www.espressif.com/sites/default/files/documentation/esp32-c3_datasheet_en.pdf) |
| ESP32-S3 |     Yes    |       Yes       | [ESP32-S3](https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf) |
| ESP32-C6 |     Yes    |       Yes       | [ESP32-C6](https://www.espressif.com/sites/default/files/documentation/esp32-c6_datasheet_en.pdf) |
| ESP32-H2 |     Yes    |       Yes       | [ESP32-H2](https://www.espressif.com/sites/default/files/documentation/esp32-h2_datasheet_en.pdf) |

> [!NOTE]
> ESP32-C2 is also supported by Arduino-ESP32 but requires rebuilding the static libraries. This is not trivial and requires a good understanding of the ESP-IDF
> build system. For more information, see the [Lib Builder documentation](https://docs.espressif.com/projects/arduino-esp32/en/latest/lib_builder.html).

For more details visit the [supported chips](https://docs.espressif.com/projects/arduino-esp32/en/latest/getting_started.html#supported-soc-s) documentation page.

### Decoding exceptions

You can use [EspExceptionDecoder](https://github.com/me-no-dev/EspExceptionDecoder) to get meaningful call trace.

### Issue/Bug report template

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](https://github.com/espressif/arduino-esp32/issues?q=is%3Aissue+label%3A%22Type%3A+For+reference%22+).

Finally, if you are sure no one else had the issue, follow the **Issue template** or **Feature request template** while reporting any [new Issue](https://github.com/espressif/arduino-esp32/issues/new/choose).

### External libraries compilation test

We have set-up CI testing for external libraries for ESP32 Arduino core. You can check test results in the file [LIBRARIES_TEST](https://github.com/espressif/arduino-esp32/blob/gh-pages/LIBRARIES_TEST.md).
For more information and how to add your library to the test see [external library testing](https://docs.espressif.com/projects/arduino-esp32/en/latest/external_libraries_test.html) in the documentation.

### Contributing

We welcome contributions to the Arduino ESP32 project!
