pin

Serial Number Pin Definitions Pin direction illustrate
1 GND - power ground
2 NC - Reserved GPIO, users don't need to worry about it.
3 RESTORE input After the internal pull-up switch is held low for at least 5 seconds, all parameters are reset to factory settings and the module automatically restarts.
4 NC - Reserved GPIO, users don't need to worry about it.
5 LINK Output Connection status indicator pin: high level indicates connected, low level indicates disconnected.
6 BAT_DET input Battery voltage detection pin
7 RESET input Reset pin, low level reset
8 WKP input The default low level indicates low-power mode, during which serial communication is disabled. Pulling the level high inputs normal operating mode, enabling serial communication.
9 RXD input Serial port input
10 TXD Output Serial port output
11 GND - power ground
12 VBAT - Positive power supply, 2.5V~5.5V, 3.3V recommended.
13 NC - Reserved GPIO, users don't need to worry about it.
14 NC - Reserved GPIO, users don't need to worry about it.
15 NC - Reserved GPIO, users don't need to worry about it.
16 NC - Reserved GPIO, users don't need to worry about it.
17 NC - Reserved GPIO, users don't need to worry about it.
18 GND - power ground
