BGA - fun to solder at home.
No open source board design.
No docs.
What happens if you put them in power chain? 13 chips should feed nicely from 12V PSU - I calculated 1877A of current @ 0.87V - can they handle this?
So far I saw only 1 successful design with high current chip - MrTeal's HF board!
I also got a reply saying do a go public shortly.
If we go by their November boards with 8 DCDC modules @ 40A
That's
320A@0.8-0.9V or around 300W. Per board of one chip, that's only 25-50% of the power density of MrTeal's Hoppin Habs. But if it's worth doing, overdo it by 50+% for them overclocking people
So say
480A@0.8-0.9V or about 430W
For 180 GH, unless you don't pay electricity, don't expect any ROI.
I hope they can run at something near 1W/GH or they are useless for most of us.
The point is what hashrate will we have @ 1W/GH
