https://devzone.nordicsemi.com/f/nordic-q-a/79898/how-does-saadc-measure-battery-power-through-vdd-pinHi I want to measure the battery power by using SAADC to measure the value of VDD，The battery to be considered is 4.2V or 3.7V lithium battery，How should the circuit be designed？Thank you.en-USTelligent Community 13Thu, 23 Sep 2021 11:38:00 GMThttps://devzone.nordicsemi.com/thread/330824?ContentTypeID=1Thu, 23 Sep 2021 11:38:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:22021b97-b3c9-4dc7-b876-f492b1d8bc50SwRa<p>Hi,</p> <p>Nordic has a <a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/measuring-lithium-battery-voltage-with-nrf52">blog</a> on how to measure Lithium Battery voltage with nRF52. I believe this will help you to design the circuit. Kindly let me know how it goes.</p> <p>Kind Regards,</p> <p>Swathy Ramakrishnan</p><div style="clear:both;"></div>
