https://devzone.nordicsemi.com/f/nordic-q-a/104692/strange-current-consumption-with-nrf52-dk-system-off-demoHi there, I&#39;m trying to achieve the system OFF current consumption on the nRF52-DK which is stated in the datasheet as 0.3uA with no RAM retention. I&#39;m running the nRF5x system off demo, using the nRF Connect SDK v2.4.2, measuring current usingen-USTelligent Community 13Mon, 16 Oct 2023 12:24:57 GMThttps://devzone.nordicsemi.com/thread/450563?ContentTypeID=1Mon, 16 Oct 2023 12:24:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61bb20d8-023c-4bf4-a206-471a1b99bba8Jared<p>Hi,</p> <p>Can you try to configure the PPK2 in source mode and then set the output power to 2V7 and see what you measure?</p> <p>This is what I measure with a unmodified system off sample and powering the board with 2V7.</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1697459015606v1.png" alt=" " /></p> <p>Note that powering with more than 2V7 at the external supply header will cause the nRF52 to be at a higher voltage potential then the rest of the board, resulting in extra current flowing from the nRF52 to the rest of the devkit. Therefore use 2V7,</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
