About this board
Inside sits the ESP32 - a dual-core Xtensa with both Bluetooth Classic and BLE.
At $30.00 it's on the expensive side for an ESP32 board - most land around $20.
Around the module: 8MB (QSPI) PSRAM, a microphone (3-mic array), a speaker connector, an audio codec (ES8388), an amplifier and EN/Action/Vol+/Vol-/Mute buttons.
The ESP32-LyraTD-DSPG is an advanced voice development board featuring the ESP32-WROVER module. It integrates DSP Group's DBMD5P digital signal processor for high-performance voice processing, making it ideal for far-field voice recognition applications such as smart speakers and AI-powered voice assistants. The board supports Wi-Fi and Bluetooth connectivity, an onboard audio codec, microphone array, and multiple peripheral interfaces for seamless integration.
- DBMD5P dual-core programmable voice DSP (DSP Group) for wake-word detection and acoustic echo cancellation
- Three-microphone (DMIC) far-field array on a detachable sub board
- RGB LED ring (Echo Dot-style) driven by an onboard LED driver
- 3.5mm earphone/headphone jack with audio routed through the ES8388 codec
- Two-board design - main board plus sub board linked by an FPC ribbon cable
- Optional Mini DIN connector for an external microphone cable (not mounted by default)
- Cloud voice support - Amazon AVS, Google Dialogflow and Google Voice Assistant
