This user guide provides information on the ESP-LyraT-8311A extension board. This board cannot be bought separately and is usually sold together with other Espressif development boards (e.g., ESP32-S2-Kaluga-1), which will be referred to as *main boards* below.
|
|
|
|
The ESP-LyraT-8311A extends the functionality of your main board by adding sound processing functionality:
|
|
|
|
- Audio playback/recording
|
|
- Processing of audio signals
|
|
- Programmable buttons for easy control
|
|
|
|
This extension board can be used in many ways. The applications might include voice user interface, voice control, voice authorization, recording and playback of sound, etc.
