Will this fit on this mobo?

As long as there is enough space inside your tower, then yes. M.2/2280 is the biggest, pretty sure the "80" in 2280 means 80mm (millimeters). Since you didn't link the Mobo I had to look up your profile, and the MOBO you linked in other question did have an M.2 socket so Tower(Case) size is your only limitation.
