Just a question BKKcoins... will each board have a serial / id number?
I don't think each board will but possibly each PIC chip may, stored in it's flash memory.

+1 for USb serial so we can distinguish multiple boards in cgminer Wink
I think probably each USB chain will appear as one unit. Not sure yet as I haven't got into the cgminer code, but if you have a dozen or two boards you don't really want a display with 12-24 lines of 300MHz each - or do you? I wouldn't. And what about people with 60 boards on one chain...

Found some very cheap potential heatsinks, would they dissapate enough heat though?

130x180x60mm
Those are smaller than you indicate by 10x. 13mm not 130mm. They may be good as one per chip but they wouldn't work for the whole board (obviously). There's a lot of these RAM/VGA chip coolers out there. They may work per chip but once you add them up you end up spending more than one big heat sink. (I'm looking for a nice blue cool looking one for the K1 however, about 1"x1.25").

Can someone verify this company? http://www.pcb-assembly.com.tw/contact.html
I'm seeing very good prices for pcb printing in mid sized orders, for 100 printed boards like $9.3
"Effy Deal Global" - with a name like that I hope they're not real. But who knows.
The price doesn't surprise me at all. I'm expecting to pay $2.70 each in qty 100.


Unit error doh. I only just woke up sorry.

You say it might cost but tis a pack of 8 and if you buy three pack the price drops to $1.88! blue ones, a bit dearer tho! although they are a bit bigger 15x15mm



Also, for the k16s; are there many raised components on the back of the board? IE will we be able to use a flat heatsink that is bigger than the total board footprint, got an old TEC waterblock I'd love to use!
