    Hi,

    I am trying to use a sensor at 5v with the 3.3v LoRa Mini Ultra pro board. I’ve successfully powered the sensor through the 5v pin, but I was wondering if I could switch the 5v pin on/off (HIGH/LOW) to save current since I’m using a battery for this project. And how would I define the 5v pin in my sketch (powerPin 5v?). Or are only digital pins able to be turned on/off and would I have to use a bi-directional logic level converter to do this?

    If there’s any guides on this, any link would be greatly appreciated.

    Thanks,

    Jatinder Mann
