The MCU circuitry was designed using &quot;Circuit configuration no. 6 for CKAA WLCSP&quot; in the nRF52840 Product Specification. I&#39;m using ncs 2.1.0 and vscode .

Between advertisements consumption is 24.40 uA. [/quote] <p>Peripherals draw ca 20uA when they are enabled. This is also the case for GPIOTE IN events. So I guess that your power draw is due to either of these.</p> <p>First, can you set the nRF chip to <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/boards/nrf/system_off/README.html">system OFF</a> and test your measurement?<br />This is a way to get a baseline for the measurement.</p> <p>Regards,<br />Sigurd Hellesvik</p><div style="clear:both;"></div>
