https://devzone.nordicsemi.com/f/nordic-q-a/78710/how-do-i-measure-the-total-power-consumption-of-the-nrf52840dk-gpios-includedHello everyone, for a low-power application, I need to evaluate the total power consumption of the nRF52840 Dev Kit. To verify my measurements, I set one of the GPIOs to toggle from high to low. I tried then to measure the current like described hereen-USTelligent Community 13Thu, 19 Aug 2021 13:49:48 GMThttps://devzone.nordicsemi.com/thread/325770?ContentTypeID=1Thu, 19 Aug 2021 13:49:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed75b5d4-6567-4d1f-9215-26064cb829b0Carl Richard<p>Hello!<br /><br />If you have setup the board according to the <a href="https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/hw_measure_current.html?cp=4_0_4_8">Measuring Current documentation</a> you should be able to measure MCU&#39;s total current consumption, including GPIOs. Have you cut SB40 (as instructed in <a href="https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/prepare_board.html?cp=4_0_4_8_0">Preparing the DK</a>)?<br /><br />I noticed that you linked to the setup instructions for the nRF52832DK. Please make sure that you follow the instructions meant for the nRF52840DK, which I linked above.<br /><br />Best regards,<br />Carl Richard</p><div style="clear:both;"></div>
