ESP32 Forum

ESP-IDF version 4.4, currently in development, will include support for the ESP32-S3 chip. This post lists the status of various ESP-IDF features on ESP32-S3.

For each feature, the status (Supported/Not supported) is given. An internal issue reference (such as "IDF-1234") is listed at the end of the feature description to help us keep this list up to date.

This list will be updated as the support for ESP32-S3 is being developed.
