    Vbat vs. Vin power teensy

    Hello,

    I am using teensy 3.2 in real-time application without computer, I would like to know what pin should I use to power the teensy? I see two pins, Vin and Vbat but I don't know which use to plug my battery.
    Thank you in advance

    Vin (that's what I use).

    Vbat is not for powering the Teensy but for keeping the RTC running with a C2032 battery while the Teensy is not powered.
