nRF52840 vital sign

I designed my first nRF series PCB.

I checked DEC1 ~ 6 voltage is fine, but the xtal pin is stable.

What is the next step to check?

  • Hi,

     

    What are you looking for? Are you just verifying if your design is working as intended? If so you can just try to flash it with a simple example, e.g. radio test example, and see if it runs as expected.

     

    By the way, even though it seems to run as it should: C39 shall be 100pF.

     

    Best regards,

    Andreas
