    Teensy 3.2 power supply issue

    The Teensy 3.2 does not power up with VIN and ground? I use a 5V power supply. Thanks for help

    Maybe it's a problem with your sketch. Who knows. You did not show it. Do you have something like a while(!Serial) in it?

    Be sure, it works without USB. You're not the first one who uses it without USB.
