Chi tiết sản phẩm
ESP32-LyraTD-MSC is designed for smart speakers and AI applications. This audio development board consists of two parts: the upper board, which provides a three-microphone array, function keys and LED lights; and the lower board, which integrates ESP32-WROVER, a MicroSemi Digital Signal Processing (DSP) chip, and a power management module.
ESP32-LyraTD-MSC implements voice interaction and cloud-on-demand services for smart speaker applications, human-machine interaction and image recognition for AI applications, as well as interconnectivity and real-time feedback for smart home devices.
ESP32-LyraTD-MSC facilitates the quick and easy development of dual-mode (Bluetooth + Wi-Fi) audio solutions, as it supports one-key Wi-Fi network configuration

Provides power supply to the whole system. It is recommended that the system be connected to a power adapter for sufficient current supply.
Provides power supply to the whole system when the USB power interface is not used.
The development board integrates the AP5056 power management IC to support battery charging.
Turn on the switch and the system will be powered on.
Turn off the switch and the system will be powered off.
An I²S bus transmits audio data between ESP32 and the DSP.
This is a powerful, general-purpose, Wi-Fi+BT+BLE MCU module, targeting a wide variety of applications ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.
This audio co-processor is used for Automatic Speech Recognition (ASR) applications. It captures audio data from an external microphone array and outputs audio signals through its Digital-to-Analog-Converter (DAC) port.
ESP32, as an I²C master, can access slave devices via the I²C bus.
ESP32, as an SPI master, can access the DSP to read/write data via the SPI bus.
Used for plugging in earphones.
Supports two external speaker outputs.
This audio power amplifier sends audio signals from the DSP to external speakers for playback.
This fixed-frequency DC-DC voltage booster powers the audio driver.
The development board supports a Micro SD card in SPI/1-bit/4-bit modes, and can store or play audio files in the Micro SD card.
This standard JTAG interface is compatible with the ESP32 programming board and supports debugging functions.
An upgraded version of the CP2102 chip supports USB-to-UART conversion.
This programming and debugging interface of ESP32 is compatible with the ESP32 programming board.
This is a normal USB communication port between PC and ESP32 module.
