Can your boards be used for Bitfury or someone else's chips easily?? Heres hoping so 
The only one that likely to work like that is possibly a Gen2 Avalon. Definitely not BitFury. If I were doing a BitFury board, which I'd like to, then I'd redesign as there are major differences in almost every way.***
Thanks, Everyone for kind words and support.
There's some errors in K1 Nano package footprints on a few parts. I'm going to review them again before posting a parts list update or board revision. Looks like a few parts have 0603 pads for 0402 parts, which is probably workable but not ideal.
My K1 boards have now arrived in Bkk and I should be going to get them within a few days. I'll need to cut them down before packing and shipping.
