Hi,

I would to test the nRF52840 using its DK with the cell battery CR2032.

Could someone describe what are the steps to configure the DK in this way?

Thanks

You should just have to make sure that the "nRF power source" switch is in the middle on "VDD" as the source, remove the plastic film tab from underneath the coin cell, and turn the main power switch on. There's nothing extra you have to do in software or anything like that.

Doing what I said above and flashing the unedited blinky example works on my DK.
