The tiny g3 routers are worth looking at. They have WiFi, Ethernet and USB,
cost very little and will usually run wrt54g Linux. Can be rather short on
memory though.

Fits very nicely into a 5370 in fact. :)

If you can acommodate SO-DIMM connectors, then I probably would go for
modules by Toradex[1] or aries[2]. I know that both companies do a good
job of getting complete support for their SoCs and the modules upstream
(very important if you want it to just work) and I also know people I can
kick if something doesn't. A friend also pointed me at [3], but I don't
know how good they are.

Generally speaking, if you google for "ARM SOM" you will get lots of
results, some of them specially made for industrial environments.
The connectors vary a lot and are too often high density connectors.
Though usually not going below 1mm pitch. SO-DIMM has kind of become
a standard formfactor for a lot of those modules (but all with
different pin-outs!). Outside the ARM sphere, there is very little else.
MIPS processors are mostly networking and video coding SoC's, so probably
overpowered for your application. There are the Intel based Minnowboards,
but they are bascially full fledged PCs with low power consumption.
(I have a Minnow Turbot here, I really like it, tiny as it is, but it's
a heavy handed beast compared to the ARM boards)

Hi

There are a nearly infinite number of ARM based modules and boards. They all are very much
a “same / same” sort of thing. They are far more alike than they are different. That’s not to say
that they are interchangeable, far from it. The issue for low volume is often more the toolchain
(and it’s cost(s)) rather than the hardware.

There do seem to be a lot of small SBCs out there.  I have used boards from
Technologic Systems, http://www.embeddedarm.com
and EMAC, Inc, http://www.emacinc.com

They have numerous models for you to look though.  Some various features:

• SBC or SoM/CoM on baseboard
• Various form factors including PC/104
• Usually with RS-232, USB, GPIO, Ethernet.
• Many without video.
• ARM processor
• Many with industrial temperature range
• Linux and development environment provided (may not be latest)
• Lower power then BBB.  One model runs at 0.5 watts.  Many around 1.

Prices generally 2 or 3 x BBB prices.

If you are going to go battery powered, I would also recommend staying away
from Linux, go with something like a 32 bit PIC32MX or PIC32MZ.  Full
Ethernet stack, RTOS if you need it, can do deep sleep down into the
microamp range when not active.

Having a full blown os is nice when all the processor is responsible for is
house keeping and storage. You also get plenty of RAM for buffering prior
to writing to persistent storage, like an SD card. That said I have found
SD cards to be fusy, at least the microchip FAT libraries. And write cycle
times are random sometimes being 0.5 seconds, which means you need to be
able to allocate memory the equivalent of a few seconds worth of data for
buffering (not an issue on linux systems).
