A lot of shields and devices will not work with this voltage. How can I use existing shields? It would be great if the Arduino team could make a version with level shifters so the large amount of boards could just plug in. I can not use the Due in existing project without major modifications beca…

I'm sure someone could modify one of these shields with level shifters.
