I just pushed up the QFN variant. I renamed the k16 directory to k16s and added k16q.
Also added a new K16Q-3D.png image file in docs.
***
I could do a limited edition signed and numbered run of 3x K1 and 3x K16 and put them on BitMit for auction.
They would be shipped out when the first batch gets to me with free registered air mail, or EMS at added cost (usual minimum EMS is around $20). Or something like that. Maybe run for 7 days?
The first batch of K1 will be special WHITE boards. How many I run like that will be determined by initial pre-orders placed on the web store. There will be single and 4up options. The 4 up you will need to cut.
***
I ran my board for a while at 350 MHz but it was getting too high an error rate so I stopped. It was about 20% errors. I think the new board may help with that as I have wires hanging around and no filtering on data/power.
Now I've been running at 320MHz with very few errors for a few hours. Seems to be very stable at 320.
How many can be chained depends on testing not yet done. In theory the data rate allows for a lot, the addressing allows for ~100, and the signal length/degradation and also how much impact it has on the master mining. If that works out really bad then we can always use a K1 without ASIC as a master. It has the same I2C function (allowing K1s to be chained without USB, or with USB as power only). A K1 as master would be very cheap since it only needs a few parts installed. (PIC, 2 resistors and only 1 reg. with a few caps).

1) Yes. A new chip from Mouser or Digikey (or others) won't have Bkk's code on it, so how will it possibly interface with the ASIC chips? If you don't want to flash it yourself then you should wait for Bkk to announce sales of flashed chips. If you are buying a completed board from a vendor then they should handle the flashing for you and it will "just work".
2) Yes. The boards have the capability of linking together and using only one USB connection. I cannot tell you the max amount but the general idea is that the "slave" boards will communicate their results to the host through the "master" board that the USB cable is plugged into. There won't be any wires involved, there will be connectors on the edges of the boards that will plug into each other. Although if you wanted wires instead of a connector I suppose that would work too.
Thanks for handling that. It's all correct info. 2) Yes. The boards have the capability of linking together and using only one USB connection.
