Expert kit power supply

Hi Dialog.

I want to use a coin cell battery as power supply for the expert development kit. I connected the jumper to J14 to choose the coin cell battery but the DA14580 does not work (the voltage between the supply and ground header is close to 0). Could you please tell me what else should i do in order to supply the DA14580 from a coin battery?

Thanks in advance!

Hi Kostakis

Hi Kostakis

Please place an extra jumper to J13 header in position 1-3 for boost configuration or 3-5 for buck configuration.

Thanks MT_dialog

I have a pin from 3-5 on J13

I have a jumper from 3-5 on J13 and from 2-3 on J14 and it still isn't getting power from the coin cell.

Hi JBaczuk,

Hi JBaczuk,

There is no other jumper configuration for operating with the coin cell in buck mode. Have you tried using a different battery ?

Thanks MT_dialog
