Is this micro ATX or ATX?

Yes this is a micro atx mother board and is able to be over clocked if you was to want too. This is a great mother board on my opinion.

The yellow line in the bottom left of the pictures, is that a led light?

Yes, it appears more orange than yellow on my board. You can set it to on/breathing/off in the settings.

does this board ddr3 memory?

No this board requires DDR4 mem

Can you overclock a Ryzen 1600 to 4.0GHz? Ram to 3200MHz? Would a GTX 1080 TI work?

None of this applies directly to the montherboard. All of these would be yest as long as: A: The R5 1600 is good enough quality to hit 4 B: The RAM is in the approved list by Gigabyte for the BIOS C: Have the appropriate PSU

does this support boot from m2 ?

yes, I got a WD Black 512 and have it as my boot drive. However, it seemed to disable the bottom two SSD ports in the process. I wanted to continue using my sata SSD and had to plug it in to the other ports to find the drive. Not sure if this is intended behavior or not.
