  • Any voltage divider resistors, filter capacitors?" ... guess Puck does not?

    The nRF52 chip has some kind of internal voltage divider for measuring the voltage on VCC - I can't remember exactly sure how it does it internally (you could look it up) but normally there's no problem at all measuring the voltage - there's no external circuitry needed

    I surely once mixed +/-

    That won't have helped for sure!
