Hi@kc23
I checked this module and seems like only the pin-s need to be control.
Control pin S allow two operating modes to be selected:high-speed or silent mode.
1.high-speed mode is the normal operating mode and is selected by connecting pin S to ground,It is the default mode if pin S in not connected.
2.In the silent mode, the transmitter is disabled.
so if you connect the pin-s to ground then you don't need to configurate it.
