Capacitors on Pin 37 and Pin 38 - nRF52832

[Francesco_M]

Dear all,

I'm designing a layout with nRF52832 and in my layout I didn't use pin 37 and pin 38 (P0.25 and P0.26). I noted that in PCA10040 v1.2.1 development kit there are two capacitors of 25pF connected to these two pins towards ground. I found that these two capacitors are for Errata 138: RADIO: Spurious emission on GPIO exceeds limits in radiated tests and bjorn-spockeli in a forum of about 1 years ago suggests to put they to ground if not used, can you confirm that I can connect pins 37 and pin 38 to ground if I do not use they?

Many thanks in advance

Hi Francesco, 

Yes, if pin 37 and 38 are not used you can ground them.

Best regards

Bjørn
