Yes this needs to be know.... I just spend 2 hours trying to figure out if I was pulling to much(using more then half the total pins) from the Teensy that it would fail to reboot after flashing....... Turns out its because im using pin 33 as in input.....
So glad im testing this with solder-less boards instead of dropping the $250 on the blank boards.
