[Arm-netbook] Ethernet with pass-through card

[Stephen Paul Weber]

Does the EOMA spec have ethernet? I forget. Neither housing lists USB ethernet as a thing it has, which seems odd if not (especially for the desktop housing)‎. Having an ethernet port in the bargain would make the pass-through card pretty exciting.

No, EOMA68 doesn't have Ethernet. But it does have USB, all the way up
to USB 3.1.

I think you need to buy an additional Ethernet-to-USB adapter.

Would be nice if such an adapter were part of a housing, but I realise
there's limited resources for the housings already on offer. Thoughts for
the future, I suppose :)

yeahyeah. LAN9512 on-board, so you don't lose the number of USB
ports. the BOM in volume of the micro-desktop is going to be around
$6-7. a variant with a USB-ETH on-board would be around $2 more and
the casework would have to be slightly larger... big redesign,
different product basically.

That's going to be hard-wired to a USB hub, I presume?

Would it not be better to provide one or two internal USB sockets, into
which one could put an Ethernet USB-stick if that's what one wanted, but
would also allow one to alternatively add a wifi stick, or bluetooth, or
say a chaos-key: http://altusmetrum.org/ChaosKey/

Cheers, Phil.

the LAN9512 is an odd IC which is itself a 2-port USB hub plus an
ETH-PHY all in one package. so it could be used *as* the USB hub,
taking up one of the 2 EOMA68 ports but then providing 2 more, so
you'd get 3 external USB ports on a micro-desktop-upgraded PCB.

ah good point - just like in the laptop housing.

yyeah let me think about that - space-wise it would be quite a bit
larger than the micro-desktop. more of a macro-desktop...

i had to take it off the standard, it's explained in the questions
and in more detail in the ecocomputing whitepaper
