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.

Hi, explorer232, greetings from Czech Republic!!!

As we talked here before, I'm definitely interested.
I made a little simple investigation about return of invested capital and avalon looks good for now. (Real parameters will be different, but for imagine and comparison it's enough.)

Where are you based
I'm in europe
We ahve PCB and assembly organized for K16 , also we have machining and sheet metal shop in hand

Hi, I am from Slovakia.

Today I make video whitch is presenting communication between PC and miner. Board generate random nonce for testing interface only because I am still waiting for avalon asic. Between two jobs is 10 miliSec delay and board send debugging data to another usb so only cca 7Gh/s rate is reached.

Are you releasing the diagrams at some point or just gonna be selling the boards ?

I have a rather friendly assembly plant here in the uk now, or are you aiming for these to be hand toasted and/or home etched ?

Hi,
sources will be released as soon as possible firstly for sponsors

At the beginning hand tousted PCB but I am asking for assembly plant.

UPDATE:

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

)

Very encouraging. Watching. Your work pace is admirable. I have high hopes that your time to market will enable many to deploy these ASICs at the given hash rate while it can still earn, given the rate of rise of difficulty we are now seeing.

1 of my samples from batch 1 (early july est) is now promised to this project.

Ill get it to op quick as I can.

Nice move dude - :hi5:

Hi, I am slightly modify the specifications of this project. Max. hashing power will be 9Gh/s. It will contain three avalon modules - each 10 chips per board.

Avalon module will be powered from onboard 108 W DC/DC converter.

Hi,

any plans to extend to >100 Gh/s in the future?
With a dedicated power distribution board driving more then a 30 Avalon chips, for example!?
The Cortex M3 CPU should be able to handle more, am I right?

Thanks

Thank you very much

I got some questions about bugs on the power board, previous figure of power shield is not final pcb but only some circuit layout.
Complete board is visibled on the last picture. (There is still some 'small errors' about the crystal oscillator).

PS for interrested people
On the picture with serial console are two mistakes that were fixed but there is old picture.

Wow, great job.

Do you need any help with this project?
It looks like you are moving ahead very quickly.
