Are D0 and D1 used on a Teensy 4.1

Are the D0 and D1 pins available for use on a Teensy 4.1 or are they dedicated?

They aren't dedicated like those on an Arduino. The Serial interface goes directly through USB and does not use pins 0 and 1. Those pins can be treated just like other digital pins. They are also the Serial1 device if you want to use it.

They're regular pins, not tied to the USB in any way (as they are on Arduino Uno, Mega, Nano).
