The Arduino Due board operates at 3.3 V. However, there are many sensors that operate at 5 V. I believe I could use the 5 V pin on the Arduino Due to output 5 V as the power source of these sensors. Is there any issue I have to think about regarding the outputs of the sensors? Their output signals are at the 5 V level, so the board could be damaged? Let's say we refer to a sensor over SPI connection. The MISO, MOSI, SCLK and CS signals need some kind of voltage leveling between the sensor and the board?
