There are companies in the uk that will make boards, small quantities are expensive, but the price drops rapidly for bigger orders.
also lots of guides on utube for etching boards.

Did you think about an optional second 5V access? Because USB is limited it could be a possibility to attach an additional psu.

I did think about it, but at this time it will most likely not be necessary - most people would either use a powered USB hub (and those now easily deliver 1A and more per port) or use USB3 ports.

In one of my tests I used a powered USB2 hub where the power brick provides 3A (plus 0.5A from the PC) and that was sufficient to attach and run 3 devices, and actually push them all the way to their limits. So by just not using all ports you leave the extra power for the ports that are in use thus achieving the same effect as if you use 2 ports simultaneously.

Plus, the extra USB connector would get in the way the simplicity idea Smiley

I'm definitely going to get set up for a DIY build and my challenge to myself is to see how low I can keep the costs.  Now that I've seen that the NF2 is in the pipeline I'll wait for that to be available.

vs3 - I'm assuming it's a 2 layer board and that the back is just ground?  Thinking about the viability of etching my own boards Smiley

Can anyone point me in the right direction to source a small number of bitfury chips (probably about 5 - 10 of them) ?

If I'm successful anyone in the UK interested in a DIY build kit of parts?

Thanks
