Key Features:
ESP32-WROVER Module
ESP32-WROVER is a powerful, general-purpose Wi-Fi+BT+BLE MCU module that
targets 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.
Micro SD Card
Supports SPI,1-bit and 4-bit modes.
Audio Output AUX_IN
Works as the input to the ES8388 codec.
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.
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.
Speaker Interfaces
Supports two external speakers.
