ESPRESSIF/ESP32-LyraTD-MSC WiFi & Bluetooth Audio Development Board Smart Speaker AI Application -80739

The ESP32-LyraTD-MSC V2.2 is an audio development board produced by Espressif built around ESP32. It is intended for smart speakers and AI applications, by providing hardware for digital signal processing, microphone array and additional RAM on top of what is already onboard of the ESP32 chip.

This audio development board consists of two parts: the upper board (B), which provides a three-microphone array, function keys and LED lights; and the lower board (A), which integrates ESP32-WROVER-B, a MicroSemi Digital Signal Processing (DSP) chip, and a power management module.
