Due pull-up resistor to 5V?

Hello.

SAM3X8E runs with 3,3V but there are only one 3,3V pin though many 5V pins, what would happen if I put a 10k pull-up resistor from a digital pin to 5V?

Hello Microzod,

From the overview of the official Arduino Due board:

http://arduino.cc/en/Main/arduinoBoardDue

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.

What does it matter how many 5v pins there are? Do you have a need to pull up to 5v?

Hi.
Sorry I plum forgot I posted this.

Yeah I see know the obvious answer.

It just seams difficult to have a board that runs at 3,3V and not be able to use the VCC pins at the end of the double row pin connector, when testing things and plugging things directly into the pins as I often do it bugs me cous I need to stretch all over the board to the one 3,3V pin, that's all.

Thanks for answering.

regards
