After playing around with the Efika for a while, I still think the design is rather well done. In my dreams of course I'd like to senn an usb 2.0 host onboard, but this might introduce unwanted costs).
But what annoys me is the power supply. Th edesign is all tiny and low cost, but if you add pico psu it will add quite some bucks to your spendings and if you go for another atx psu you get big ugly unhandy boards.
Thus, my suggestionis to include the needed atx logic on the Efika board itself (will introduce costs, but my (rather naive) guess is that these cost will beenfit in the overall effort) and change the power supply to a plain 12V DC input.

And what if you want to use it in automotive areas whereby the input range needs to be higher?

Or you can't get 12V from some industrial application? :)

There is a drawing board for an Efika which runs using Power over Ethernet - you can drag some 10-12W off a PoE injector on the same cable as the networking You can buy injectors from Linksys, D-Link and everyone else at most electronics stores (Best Buy in the USA for instance).

Building a PSU onto the board is something we could do if you had an industrial need for it and a large order, but the board is more flexible this way. The ATX standard is far more prevalent and off-the-shelf and full of choice - take PicoPSU as an example - than forcing people to use 12V DC.

Your suggestion has been noted :)
