We would like to use CR2450 coin battery for power supply. Can CR2450 coin battery be used to supply nRF52832 module? Pls advise. Thanks! Looking forward to your reply!

In that case this battery should be fine. But if you use a DK, then I&#39;m not sure that this battery will fit the casing.</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/168122?ContentTypeID=1Mon, 28 Jan 2019 05:05:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9f7126f0-2516-4563-aa3c-8195861e2003Ashish<p>Hey,</p> <p></p> <p>Please take a look at the product specification on the&nbsp;<a href="https://www.nordicsemi.com/DocLib">documentation page</a> for nrf52832.</p> <p>The voltage&nbsp;supply range for nrf52832 is between 1.7V - 3.6V</p><div style="clear:both;"></div>
