I doubt if it's redommendable to link anything resembling an
integrated circuit, not to speek of a mama board, *directly* to the
"12-V" power system of a car - there are enormous voltage surges (and
drops!); you'd need some kind of stabilizing buffer. And as you need
different Voltage levels for the MoBo/devices, there's probably no way
around some kind of converter anyway. Probably not too difficult,
electrically, but it should sure have its own accu/battery with
sufficient capacity.
BTW, Belgian national police ("gendarmerie") became the joke of the past
year with their new vans for alco-test: the "sophisticated"
(computerized) gear was fed by the cars' power system and showed such
strong deviations (depending on the motor's regime, use of heater and/
or headlights, etc) that for this very reason that they had to trash
a number of some two-digit thousands of "measurements".
