Power supply of Due

Official Hardware Mega Due

Hi,

I am new here and I am a bit confused about the power supply of Due.
From the spec, it can not exceed 3.3V otherwise it may damage the board.
However, if I search outside, the recommended power supply is either USB (typical output is 5V, am I right?) or DC adapter with maybe 7-12 V.

Does it mean there are some voltage divider or similar circuits on the Due board?

Thank you.

Yes it is a voltage regulator that burns off the excess power to convert the input voltage into the 3V3 that the processor needs.

Thanks a lot Mike.
