If pin A4 and A5 are not con-nected (NC), output state will be on-board ceramic chip antenna.RF In/Output Pin A4 Pin A5On-board ceramic chipantenna outputNC or 3.0 V – 3.6 V (typ. 3.3V) NC or GND (0 V)Module 50 Ohm RF-padoutput (pin 16)GND (0 V) 3.0 V – 3.6 V (typ. 3.3 V)4 The supply current must be limited to max. 1A5 The capacitive load should not be larger than 50 pF for all I/Os when using the default driver strengthsettings. Large capacitance loads generally increase the overall current consumption.
