due outputs 3.27V , why?

Hi,
I started with DUE.
Everything is fine, but all outputs , when HIGH, give 3.27V instead 5V.
Where is the problem?

There is no problem, the processor runs at 3.3v , so outputs can only go from 0-3.3v max . Tolerances in power supply etc means 3.27 is fine!

Thanks,
How can I change it to normal 5V?

For digital outputs, use a logic level shifter.

Thanks.
