NOTE

  • Only Digital OUT, 3V3, and GND are connected to WisConnector.

  • An optional 3V3_S supply voltage can be used to turn ON or OFF the RAK12006 module through the IO2 pin. This can be helpful on low power application.

  • To disable the default 3V3 supply and use the alternative 3V3_S supply source, the resistor jumpers R1 must be 0 Ω and R2 must be NC (not connected).
