Esp32 A1S WiFi+Bluetooth Audio Module V3 Previous Esp32 A1S WiFi+Bluetooth Audio Module V3

This module supports UART interface and supports SP Bluetooth serial port protocol, which has low cost and small size.

Low power consumption, high sensitivity of transmission and reception, and only a small number of peripheral components can achieve its powerful functions.

Common Pins:

1>.Pin-1:UART_TXD.UART data output

2>.Pin-2:UART_RXD.UART data input

3>.Pin-11:RESETB.Reset/restart button

4>.Pin-12:3.3V

5>.Pin-13:GND

6>.Pin-21:GND

7>.Pin-22:GND

8>.Pin-24:P12 LED pin (slow flash when not connected. Always lit after connection)

9>.Pin-25:P12 host interrupt indication port, idle is low, the connection is high
