nRF52840DK not working intermittently

Hi,

The nRF52840DK-2.0.1 is not working/turned on.

it works intermittently, and keep on connect/disconnects continuously after sometime.

I suspect the SW9 switch is faulty.

Can you please tell me which are the tracks/pins suppose to connect when the switch is in VDD position?

Thanks,

Sujith

  • Hi there,

    Can you please tell me which are the tracks/pins suppose to connect when the switch is in VDD position?

    When configured to VDD the switch will connect VDD_nRF to NETC92_2(VDD_HV') and VSRC_NRF to VDD_nRF'. 

    it works intermittently, and keep on connect/disconnects continuously after sometime.

    Is there any specific reason for why you suspect SW9 to be the culprit?

    regards
