https://devzone.nordicsemi.com/f/nordic-q-a/97049/nrf52840-battery-voltage-measurement-in-normal-voltage-modeHi, I want to measure the battery voltage with my nRF52840 board. According to the datasheet VDDH should be shorted to VDD to normal voltage mode. (Circuit 1) So, in order to measure battery voltage, it is necessary to use a voltage divisor connecteden-USTelligent Community 13Mon, 27 Feb 2023 08:20:14 GMThttps://devzone.nordicsemi.com/thread/412168?ContentTypeID=1Mon, 27 Feb 2023 08:20:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c63663e9-e5e3-4937-94b4-32008625133eketiljo<p>You can make a very low current voltage divider like this:&nbsp;&nbsp;<a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/measuring-lithium-battery-voltage-with-nrf52">https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/measuring-lithium-battery-voltage-with-nrf52</a>&nbsp;</p> <p>Circuit 2 won&#39;t work.</p> <p></p><div style="clear:both;"></div>
