[hpsdr] Nano-ITX

[Eric Ellison]

Brian

Yes, these look VERY nice. I am using a Asus P4P800VM for several years in
an Aria case, with a 3.2 gig processor. I've been pleased with it's size and
performance. 

I think the Nano's have better performance than the 1 gig processor implies,
but have not followed it recently. The size is really attractive for remote
embedded systems. With Ethernet and 2 USB onboard and potential to use the
small 12 V powered PicoPSU's this would be the ideal for mounting in an
enclosure with an Atlas based SDR systet

Just dreamin of the future!

Eric

Eric,

I agree that nan-ITX boards are very small. :)  Unfortunately, they
appear to top out in the 1GHz range.

I was thinking along the lines of:

http://www.logicsupply.com/product_info.php/products_id/735

and

http://www.logicsupply.com/product_info.php/products_id/552

I'm favoring the first one.  Those are mini-ITX units that support a
Core2Duo mobile chip.  Plug a decent dual-head graphics card into the
slot and you'd have a very competent system for running PowerSDR.
