      Hi All,

      From within REXYGEN on the Monarco HAT. Can you sample/read the supply voltage to the HAT in anyway?

      Cheers

      Mike

        Hi Mike,
        thanks for the question. This is not possible, the supply voltage is not connected to any ADC converter. The only option is to use external voltage dividers and bring it to one of the analog inputs of the Monarco HAT.

        What is the motivation for such a request? Some battery/solar-powered application?

        Best regards,
        Jaroslav

          Hi Jaroslav,

          The reason is for battery monitoring. Using an external sensor is fine. Just wondering if the hat had some way of internal measurement.

          I will need it to work out battery charge etc.

          Cheers

          Mike

            Hi Mike,
            thanks for clarification. I have no experience with that, but the Maxim MAX1721x with 1-Wire interface seems to be ideal for such a project with the Monarco HAT.
