Don't limit your search to things that doen't have what you don't need.  It
may be cheaper to get a high volume part and ignore the sections you don't
need.

I learned that ages ago when a TI rep suggested a codec chip for an A/D.  We
just ignored half the chip.  It did what we needed at a lower cost that any
of the alternatives we could find.

Power consumption - it's going to be battery powered
I've been looking through the literature, and you can power down some of
the chips on most of these things.

If power consumption is an issue for you, then I would advise against
going for a Linux board, unless you either find a board that is specifically
designed for that purpose (and has the software support) or you have
a few months time to iron out the problems in the Linux kernel to
get the system to go into sleep.

It's far easier to use something line Nuttx or FreeRTOS on an
Cortex-M3 or arm9 and get that to use little power than it is
to get an full fledged Linux system to behave.

Any simple idea will be worded in the most complicated way.

Yes, that was exactly my point, There are two kinds of ARM, the A and the
M.  "A" is the kind used in you smart phone and the Raspberry Pi and BBB
and these suck up a few watts of power.  The M type is made for low power
and could run off a few AA batteries and the battery shelf life would
expire before the battery was used up.  A simple data logger could keep
the CPU in sleep mode most of the time and then it uses literally a few
micro amps.
