this is all prior to first power-up. i'm honestly slightly nervous
about powering the boards up when they're wired together like this,
because the slightest short-circuit or incorrect cable and it'll
damage things. although i do have some revision 1.0 EOMA68-A20 CPU
Cards left, i'd rather no more were damaged!

still, i've tested them all individually - it should be fine.

shorted the usb-otg 5v rail accidentally already, have to power the
CPU Card from VBUS instead... no matter, i have to replace the LTC4155
due to misrepresentation of its capabilities, with a bq24196 from TI
anyway....

that is extraordinarily cheap, very good. i also checked the cost
that they'd be able to do EOMA68 boards at, and it's 60% of anything
else i've previously been quoted: $361 instead of $600 for qty 5, and
that's a 1.2mm PCB. a 1.6mm 110x90 2-layer PCB with 6-6 mill
track/clearance and 0.25mm min drill size was $38 for qty 5 which is
about 30% of what eurocircuits quote.

bear in mind that you would still have to pay tax, duty, tax-on-tax,
tax-on-duty and tax-on-tax-on-duty... oh, and shipping. and
tax-on-shipping. and tax-on-duty-on-tax-on-shipping. all of which
could well end up adding almost 80%+ to the cost.

time-wise they look pretty fast, eurocircuits do a typical 7-day
turnaround (these guys are 3), shipping from eurocircuits is often 2-3
days (and is only once a week for the 7-day production), so actually
even though shipping would be with DHL international from china, you
might actually end up getting it faster.

weird, huh? :)
