Package includes
1 x ESP32-LyraT Development Board
1. ESP32-WROVER Module
ESP32-WROVER is a powerful, general-purpose Wi-Fi+BT+BLE MCU module thattargets 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. For more information, please refer to the User Manual.
2. Micro SD Card
Supports SPI,1-bit and 4-bit modes.
3. Audio Output AUX_IN
Works as the input to the ES8388 codec.
4. USB-UART Interface and USB Power Supply Interface
USB-UART Interface:the integrated CP2102N-A01-GQFN28 chip is used to convert USB to UART and supports a baud rate of up to 3 Mbit/s.
USB Power Supply Interface:the working current of the Wi-Fi module is very high at peak times. Therefore, a power supply with a capacity of more than 500 mA is recommended
5. Touch Buttons
Four touch buttons are available on the development board:Play, Set, Vol+ and Vol–. Used as keys for audio functions, they bring such advantages as reduced BOM cost and design flexibility.
6. Speaker Interfaces
Supports two external speakers.
