nRF52 and battery information

cedric.requin

Hi,

I have a customer request regarding ISP1507 module (with nRF52832 integrated) and battery information.

Customer want to have battery information using LED (bicolor LED connected to GPIO with current limiting resistor).

Is it possible to know the battery status thanks to a command ? Is nRF52 able to detect the drop voltage ?

Thank you for your support.

    Hello Cedric,

    Yes. It is possible to measure battery voltage on the nRF. We don't have anything that measures the input voltage, but we have an example measuring the voltage from GND to a pin. (or between two pins if you want a different offset).

     

    Please check out the SDK\examples\peripheral\saadc example, which measures the voltage on pin P0_02.

     

    It is also possible to do limit monitoring, if you are only interested in knowing e.g. when the voltage drops below a certain point.

    Please see this case for limit monitoring.

     

    Best regards,

    Edvin
