Power consumption custom boardhttps://devzone.nordicsemi.com/f/nordic-q-a/28094/power-consumption-custom-boardI have put my code developed on a nRF52 dk on a custom board that is based on a ISP1507 CPU. We are having higher current consumption than expected, I use the exact same code on the two boards. Is there some things I should double check to make sureen-USTelligent Community 13Thu, 14 Dec 2017 20:37:09 GMTRE: Power consumption custom boardhttps://devzone.nordicsemi.com/thread/110766?ContentTypeID=1Thu, 14 Dec 2017 20:37:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7cff8625-1016-4888-9018-bdf9e6d02c1aerltot<p>Power consunption was high due to some external amplifiers that were not disbled along with a gpio that was defaulted low with and external pull-up causing a voltage divider with almost one mA</p><div style="clear:both;"></div>RE: Power consumption custom boardhttps://devzone.nordicsemi.com/thread/110765?ContentTypeID=1Thu, 14 Dec 2017 20:35:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b6f3d35a-4b05-4b7c-b4fd-472a43137b02phipi<p>Was this resolved?

If you still see ~2mA it is probably hardware related. Maybe some bad solder joints or short circuits.</p><div style="clear:both;"></div>RE: Power consumption custom boardhttps://devzone.nordicsemi.com/thread/110763?ContentTypeID=1Wed, 27 Sep 2017 10:51:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:84951c25-11cc-4c8d-acfd-e64361919283erltot<p>about 2mA more on the custom board</p><div style="clear:both;"></div>RE: Power consumption custom boardhttps://devzone.nordicsemi.com/thread/110762?ContentTypeID=1Tue, 26 Sep 2017 13:46:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2184f30e-4619-4507-b28b-a2d925bd1b59MartinBL<ol> <li>Make sure that you don&#39;t have any floating GPIOs.</li> <li>Resistors on SWD lines shouldn&#39;t matter on the nRF52.</li> <li>If the code is the same then the DCDC should also behave the same.</li> </ol> <p>What differences in consumption do you see?
