Indeed, and If I get some samples of these, some will find their way to this project
Getting samples for fury is a bit harder, lots of interest..
But a shield for those would be worth many btc

A 10 chip BF shield would be 50 GH/s. The avalon shield would be 3.5GH/s. I have a feeling I know which one would be most popular.

I thought you might be interested to know that Bitfury are doing a sample chip program for developers

Did you realease your own library to communicate with CGminer. How do you receive de work unit and how do you send it the to Avalon chip?
Im going to try to do the same with a Leornado card.

much better, 5x5 holes
nice breakout board...lets hope you can get it talking to the arduino soon
Wonder if you could use a few more feed thru under the Avalon chips to help with heat transfer.
nice work, watching this project now...
Great news !!!
Today arrived to me 1 AVALON chip from evilscoop Thank you for it Because at the moment I dont have prototype pcb, avalon arrived very fast, make a bit hack . I designed simple test board for chip and this is the result. When arrive to me electronics components I can to test the miner. This project consumes all my free time and quite a lot funds so if you think I have been helpful donations are welcome.

This is preview of final prototype PCB for avalon board:)
4 layer pcb

3D model is generated from uses script in eagle,so silkscreen (description layer) is a slightly different on the real PCB.

query
Are you building in a way to overclock ?
Avalon have stated their chips can be ramped up a bit from default

Hi, yes cores are powered from 108W adjustable DC-DC converter. In normal state ~ 2W power is used for one avalon * 30 = ~ 60W
Each module has own heatsink from the opposite side.

Very impressive. I created a similar project with small differences (well some people might see them as large). I created modular boards that could support various chips at variable power levels... it was mostly a way for me to learn the inner workings of Avalon, BFL and Bitfury ASIC's chips without actually having the chips in my possession (I do have a prototype board already professionally etched/printed and awaiting Bitfury chips; no idea how I will get my hands of them when they are released 
). I started off years ago with Microchip's MCUs and was able to visit my roots with high-end but low cost 32-bit MCUs running FreeRTOS (I started off with a loaned Xilinx Zynq-7000 devkit since I'm very familiar with ARM and Xilinx FPGAs, however an unknown person at work placed an old CRT monitor on top of the board and completely ruined everything, however I have other plans for the Zynq so I hope to somehow get my hands on another devkit).
Keep up the great work!

I have to say I don't know details of your design, but there is possibility of overclocking, as described in datasheet of avalon chip. (And discussed in other avalon-clone threads like this).
Did you think about possibility of supply voltage/clk frequency tweaking?
And second note, please think about 28(-35)GHs variant, I mean 10 avalon modules shield. You always can use 3 modules only, but benefits of modularity are known ;-)
If I can provide you any help, feel free to ask.

Hi
, in my design is definitely posssible change voltage for cores by replacing one resistor on the power board. I dont know the internal structure of Avalon, so I dont know whether external clock is used only for cores or also for internal logic.
Tweaked oscillator frequency could cause data corruption.
Your project should been encouraged! Do you need Arduino DUE boards?
I do not know the price of Arduino DUE board?
I am from China.
If I can do something, pm me.
Thanks

Hi, unfortunately at the moment this project is financing only by me. Evilscoop promised me 1 avalon, so I'm waiting for it. This week I will have electronics parts and pcb for the first prototipe.
Do u need more Arduino DUE?
cmon marto keep up lol
nice to see all the k16 assembly guys looking for other options

UPDATE:
Great news. PCB for avalon module is partly finished. (there are still needs some cosmetic changes )

Looks very interesting and will be following your thread. Keep up the work!
