Note that the Due board differs from other Arduino boards in terms of voltage level. The microcontroller in Arduino due runs at 3.3 V instead of 5 V (common in most other boards). If you connect a higher voltage to the pins, you may end up damaging the board. The board can take power from a USB or a DC plug (at 7-12 V), because there is an onboard voltage regulator, that converts this value to 3.3 V.
