Template:FAQ/Questions/matter in what direction

Does it matter in what direction expansion boards are connected as long as the right connecter is used?
Yes, connection direction does matter for all expansion boards. The expansion boards will only work when connected the right way round, even though the connector is nearly symmetrical and will physically allow itself to be plugged in backwards. The three (3) boards should all overlap each other, aligned the same way, in the sandwich configuration. Audiostix/connex/etherstix should all fit comfortably for example.

When the tweener board is used, it does not align with the other boards, but rather sticks out of the end.
