Hi,

What are those 2x2 header pins that are unpopulated?
It's connected to PB4 to PB7 on the ATMEGA16U2.

Thanks,

The ATMEGA16U2 is an IC.  It doesn't come with any headers.

I know that, but PB4-PB7 is connected to a unpopulated header on uno, mega and even due.
What is it meant for?

They say maybe an unimplemented feature.  In any case, it's just a breakout for those four pins.  Feel free to mount pins in it if you want.
I will never ask you to do anything that I wouldn't do myself.
