Frequently asked questions
Can I use 5V Arduino shields with the Due?
The Due operates at 3.3V logic and its I/O pins are not 5V tolerant. Use level shifting for 5V sensors or shields, and check each shield's logic voltage before connecting.
What input voltage should I supply?
The listing recommends 7-12V with limits of 6-16V on the input.
