Nice jobs for the Drillbit board!! it is beauty, would you do a picture of hook up of the 4 board for better understanding?
it is interesting to have more clearing picture on it. Hope this request will not bring too much work load.

I cannot see the connector for the other boards (top port?) on the model you just shown up. I can find the backplane port, the power plug, and the USB port. So I cannot figure out how the "stack" of 4 board looks like.
The ASIC board has 3 ports built in. The top port on the first board takes a data distribution board - like the FPGA board in the Avalon miner, only much, much simpler. It comes included with the initial purchase of a DrillBit board so you are ready to start mining as soon as you get it, nothing more required. But when you want to add more hashing power, this is where the DrillBit system really shows its advantages over other systems. If you want to double your hashrate to 43.2GH, just get another ASIC card and plug it into the bottom port of the first card. Its that simple. No big strings of USB hubs, no messy cables or setup changes. The data distribution card automatically registers the extra ASIC card and operates accordingly. Up to 4 cards can be stacked in this way.
This is not very clear to me. Could it be that one board is different from the others? Are there different models of "8 chips boards"? If so, I need 4 "first boards" for my 16 boards order.
