Battery connector for nRF54L15DK

Hi,

It would have been quite useful if nRF54L15DK had CR2032 battery holder to carry around for experiments. since this board does not have it any recommendation to conne4ct this DK to the CR2032 battery?

An nPM2100EK lets you hook a variety of primary battery types to the nRF54l15DK.

Thank you, how to hook in nPM2100EK  to the nRF54L15DK without using its USB power supply? probably a wiring diagram helps!

I'd check out the diagram on Use the nPM2100 EK with the nRF54L15 DK for the wiring.  The nPM2100 lets you use different types of batteries by having different (included) boards that accept the batteries and plug into the main evaluation kit board.  You'll still plug the USB into the EK to do the PowerUp config and get logs and stuff, but it shouldn't be powering it.  The wires you connect to P6 on the nRF54l14DK are what provides the power to the DK and it only uses the USB for debug stuff.

The debugger chip has to be powered and an active debug target pulls more power, too.

I have tried that with NRF51x chips, a CR2032 lasts about an hour when debugging. The finished product lasts around 60 days in active BTLE state on the same cell type.

Is it not possible to connect rechargeable batteries to the nRF54L15DK ?
