https://devzone.nordicsemi.com/f/nordic-q-a/45576/nrf52840-dk-soc-isolationHello, I am currently using the nRF52840 Development Kit and was looking to isolate the SoC for power consumption testing. I mainly want to disconnect the integrated MCU and all other parts that may influence current consumption.

It could be that the floating IC switches are causing problems. Can you try to pull VDD to ground, in order to make sure that no external components are floating? Which version of the DK are you using? I can try the same setup here on the DK version you have.</p><div style="clear:both;"></div>
