https://devzone.nordicsemi.com/f/nordic-q-a/18476/errata-138---spurious-emission-on-gpio-exceeds-limits-in-radiated-testsHi, I&#39;m not sure if I understand the new reference layout correctly. There are new NP0 12pF capacitors on pin 25 and pin 26 to suppress the spurious emission, but are they always needed or only if these pins are connected to a trace?
