no really knowing at all about all this, but... Have you heard
about the Raspberry Compute Module?<br clear="none" class="" style="">
<br clear="none" class="" style="">
It's basically the Raspberry A on a module + 4Gb Flash. I think
it's design is open and the page says it will sell for about 30$
in batches of 100, a bit more for individual purchases. It has
internal 4Gb Flash and 512Mb RAM and a 32bit CPU ). All the gpios
and everything else are routed to a SODIMM connector.<br clear="none" class="" style="">
<br clear="none" class="" style="">
I've read in the product documentation [2] that internally, the
broadcom chip does not power at all it's different parts or
modules unless they are beeing used, so if no 3D is used this part
of the chip is not powered and draining any power...<br clear="none" class="" style="">
<br clear="none" class="" style="">
Theres is still no CAN or Wifi or bluetooth, but maybe that could
be in the "mainboard". There could even be different mainboards
with/without Wifi or 3g... <br clear="none" class="" style="">

Just my 2c in case it can be useful.<br clear="none" class="" style="">

<ul class="" style=""><li class="" style="">What is interesting is the advent of low-cost Linux

the BeagleBone and RasberryPi are fascinating, but really
designed for HDMI video output - and the overhead of GPU +

we require is (<a rel="nofollow" shape="rect" target="_blank" href="http://compulab.co.il/products/computer-on-modules/cm-t335/" class="" style="">http://compulab.co.il/products/computer-on-modules/cm-t335/</a>)
- pretty amazing little device - low power, wifi+bluetooth,
dual CAN, up to 512MB RAM and 1GB FLASH, for around US$50
(in horrendous quantities). I'm working with my contacts in
China to see if we can base on a dev board something like
that. If they can make Android phones for US$50, we should
be able to get the guts of such a device for something
similar. Then, add on GSM, take it from a BOM to a product,
and we're probably looking at something still <US$150 but
with so much more. The closest thing to ideal I've found at
the moment is build a baseboard (connectors, power, CAN
buses, etc) and have slots to take that CM-T335 module and
an optional GSM module. But, I still think we can find
something on the China market even closer to what we
want/need.</li></ul>
