loooking at 2 alternatives to get to 10baseT: SPI and USB
are known solutions for both and I'm deciding.
klsi.com and the TINI SPI-Ethernet interface.
reason we didn't do it on board is for space and power: the CF slot is
almost bigger than the board. we elected to go with
Bluetooth instead. It's just not ready for release
My main intent is
to support wireless in some form, ideally 802.11, with a Gumstix borad.
That being said, since there are currently no Linux supported SDIO wireless
WLAN cards, and USB is out, I've been looking at
It looks like the PXA255
architecture supports CompactFlash/PCMCIA with no additional hardware needed
(aside from the port). Was your decision to limit this functionality due
to space concerns (obviously the CF port won't fit on the Gumstix board), or
for other technical reasons?
Would it be feasible to create a Gumsitx with those
ports exposed, or a daugher board to support the approprate
For my application, the power-draw isn't a big
concern, but wireless range and overall system cost is a big factor.
That eliminates (perhaps) bluetooth and other wireless solutions like
"wireless RS2332" (see http://www.abacom-tech.com/downloads.htm).
I really like the (elsewise) low power draw of the
Gumstix board, the fact that its a SBC with such an itty bitty form factor,
and you're adding linux support from the get-go.
