nRF52840 current ~2.4mA at besthttps://devzone.nordicsemi.com/f/nordic-q-a/83678/nrf52840-current-2-4ma-at-bestI am using the MDBT50Q-1MV2 which has the nRF52840, and have burned the Adafruit Feather Express bootloader using a J-link and the Arduino IDE. The issue is that I have not been able to get the current below ~2.4mA and that is using the systemOff(); functionen-USTelligent Community 13Mon, 17 Jan 2022 14:01:25 GMTRE: nRF52840 current ~2.4mA at besthttps://devzone.nordicsemi.com/thread/348068?ContentTypeID=1Mon, 17 Jan 2022 14:01:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e17a42ff-7140-4b61-afd1-5d90323e1a18Hung Bui<p>Hi Avery,&nbsp;</p> <p>To get out of debug mode you just need to do a power reset of the chip.&nbsp;<br /><br />I would suggest to test the board with a very simple application for example the rtc example in the nRF5 SDK v17.1&nbsp; located at&nbsp;\examples\peripheral\rtc. The example put the CPU to sleep and only wake up by the RTC interrupt to toggle a LED.&nbsp;<br /><br />If you have a nRF52 DK you can try to compare the current. It should be around 2-3 uA.&nbsp;</p><div style="clear:both;"></div>
