Status of un-used signals in nRF9160

[Venugopal.K]

Hi Team,

May I know the functionality of the below mentioned signals:

MIPI RFFE interface pins: VIO, SCLK, SDATA.
MAGPIO interface pins: MAGPIO0, MAGPIO1, MAGPIO2.

AUX pin

Can these signals be used by user or these signals are for Nordic use only?

If we don't use these signals in our circuits, what is the recommendation? Whether to leave them open or need to connect to GND?

Hi,

 

Yes, they can be used for some applications. See the description here and here.

 

If you do not use these you should leave the pins floating/not connected.

 

Best regards,

Andreas
