Excellent review and pictures 
Any ideas on how you can link them together so uses one usb controller? What PSU would be the best ?
Thanks

Glad you liked it
There is no can-bus support in this revision of the board, so you'll need powered USB hub for more boards.

Only Avalon gen1 based HEX16A requires powered hub.
With HEX16B and A2 you can used passive hub and to power even tp-link router from the boards and hub .
10x to our board designer for the efforts in this direction
