I am comparing 2 arduino mega's.
Both seam quite similar but the Due runs on 3.3 volt.

Does it mean that if i set a pin to high that it's voltage will be 3.3 volt ??, and is that enough for normal shields ? might some shields not work on it?

I am planning to use a mosfet shield to drive lots of leds

The DUE is not a Mega.

Either that or 567. 3.3 seems a lot more likely, though.

Yes, if the shield is a 3.3V shield. There are shields that need 3,3V and there are shields that need 5.0 volts.

Which MOSFET? Does it trigger at 3.3V or 5V?

There are very few shields that connect to all the pins of a Mega or DUE.
