There’s a lot of expansion card ideas floating around here that are being held back by size limitations so I was wondering whether this is a feasible solution:
An expansion card that utilises the slot next to it just for extra space and rigidity (only one side would have a USB-C connection), and a small bridge across them just for wiring.
Would this fit in all 3 laptops? Is the spacing between modules for all 3 laptops the same? And for the Framework 16, are the spacing between the 3 slots on each side the same?
One big issue is that that space comes in the form of 2 relatively disconnected areas so I am not sure how many “unpractical because of size” designs this would actually make practical.
That is probably the better option if we are starting doing non flush designs. Double stacked board may even be possible with less than 2x the thickness and you may get some extra elevated feet in the deal XD.
Only as many as fit, traces aren’t infinitely thin and a lot of them have routing constraints. Sure you can do multiple leyers and all that but if you go that route you may as well fold it over and put it in a slightly thicker card.
