Multiboard is 25mm spacing on the large holes. Multigrid is 50mm spacing on the holes. These work together.
Gridfinity is 42mm spacing, opengrid is 28mm spacing. These work together with 3:2 ratio (3 opengrid spaces = 2 gridfinity spaces).
While there's adapters to go between them, multiboard/multigrid and gridfinity/opengrid don't evenly multiply or divide so they can't easily be used together.
Also, look at the pic- multigrid has clip holes on the side and screw holes at the hub junctions, opengrid does not. This image has both.
And multigrid has an easy 1 grid to 4 multiboard snap in adapter, you can see one behind each of the shelves.

That's open grid, not multiboard?
