Many thanks for your explanations, onpon4. I’m beginning to see the light
;-) The Rombus-tech website isn’t very clear. First, I thought there were
different mini-cards you could assemble on to the main card, then I thought
"housing" was like a case, or a box, like they sell for the
A20-OLinuXIno-LIME2, with the right openings.
So, to take an example,for the EOMA68 computer card, you need to buy the
housing to have a VGA port. The VGA port is part of the housing, not part of
the computer card.
If you buy the A20-OLinuXIno-LIME2, you have no VGA port (though you may have
one perhaps, but no matter for the moment). If later they sell a single board
with a VGA port, and you still want the VGA port, you need to buy a new
single board.
On the contrary, if Rombus tech or someone else makes a housing with an
ethernet port for the EOMA68 computer card, you can keep the card and buy the
housing.
Still, I’d be totally bowled over if I was able to buy an ethernet port and
attach it myself, one way or another, but of course that would mean that
Rombus tech would make electronic circuits for various ports on their card.
At present, USB ports have been chosen since they are somewhat universal: you
can "attach" ethernet, wifi, sata hard disk, USB flash drive, etc.
Am I still talking nonsense? (I love those single boards like
A20-OLinuXIno-LIME2, Beagle Board, Novena, but perhaps, I’d better wait for
the EOMA68 computer card)
