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

el_supremo Well-known member Dec 22, 2020 #2 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. Pete
