Module Selectable RF-In/Output
Module RF-Output can be switched between on-board ceramic chip antenna and 50 Ohm RF-
pad (pin 16) output by adjusting voltage level on pin A4 and A5. If pin A4 and A5 are not con-
nected (NC), output state will be on-board ceramic chip antenna.

The supply current must be limited to max. 1A

The capacitive load should not be larger than 50 pF for all I/Os when using the default driver strength
settings. Large capacitance loads generally increase the overall current consumption.
Product Specification Rev. 1.1
The maximum ratings may not be exceeded under any circumstances, not even
momentarily or individually, as permanent damage to the module may result.
