Avalon A3255 Hashing Boards - Looking for open source or licensed board.

[Somekindabitcoin]

Had anyone created a hashing board for the Avalon A3255 or even have a working design? I would love it to put my chips on so I can keep it in an immersion tank. If you do, please reply here. Thank you.

Drillbit Systems does, I believe: http://drillbitsystem.com/

( Unless OP was actually thinking of the A3233 to begin with )

I was looking for the design so I can get it fabricated and assembled. I have 25,000 A3255 chips. I wanted to put em on boards, get my pi's and put it into a two phase immersion tank. It should give me around 95-100 TH/S of power and I think the price would be between 25-30k. I bought the chips for the price of 1 KNC Neptune and a mini neptune. Now I just need the boards and such.

Yeah, I don't think they are freely available - except for that AvThumb perhaps, as a winner of an 'opensource' contest, you'd think the files would be open source.  You can probably license the board designs though.  Just get in touch with them, or put a request for partnership out at the marketplace if nobody notices this thread (could try modifying the title a bit to clarify)

I think I will try and get in touch. Checking out Marto's pm now.

Oh, and the Drillbit Systems files are here: http://www.drillbitsystem.com/avalon/

Avalon/Canaan's design files are open source: http://downloads.canaan-creative.com/hardware/A3233/avalon3/

Very solid HW designs - unlike most of the crap coming out these days


edit: just noticed that you were referring to gen 2 chips, you can find the design files here: http://downloads.canaan-creative.com/hardware/A3255/avalon2/2014-01-19/

I haven't looked at these personally.
