*bump*
Right now i searching the forums for pcb manufacturers and designs but haven't found a thing :-)
Regarding the design question - take a look at my signature.
I can also assist you with the process if you want US-based manufacturing. PM me if you need any references.
As for EU-based manufacturing - I've already been working with Marto74 /
www.technobit.eu (as you can see from the pictures of my NanoFury NF1 miners
) and have been more than happy with the work he did.
