How to use Arduino Due? Answered

I want to use a servo on an Arduino Due like I would on the Uno (use digital pin+ground+5vpin) but I am confused about the 3.3v limitation. The Due has a 5v pin on the board along with a 3.3v, but the website says 5v is not safe for it. Does that mean the 5v pin can't be used like the one on the Uno, even though it is there?

Please heed the notes on the ArduinoCC website. You can POWER the board off 5V, but you must NOT feed the inputs with 5V logic signals.

Warning: Unlike other
Arduino boards, the Arduino Due board runs at 3.3V. The maximum voltage
that the I/O pins can tolerate is 3.3V. Providing higher voltages, like
5V to an I/O pin could damage the board

No need to treat the Due any differnt than the Uno.
