Applications Tested on ESP32

These TuyaOpen applications have pre-built ESP32 configs:

Note

Applications fall into two categories:

• Board-specific: Has a config/ subdirectory with one config per board, targeting boards with specific peripherals such as a display or audio codec.
• Generic: No config/ subdirectory — works on any base ESP32 module (ESP32 / ESP32-C3 / ESP32-S3 / ESP32-C6) without requiring board-specific hardware.
