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
