It is already pre-Program & flashed with firmware,  on its FPGA controller,
which connected to 2 / 4 Blade of Ava 2,  80 chips each.  1.5 - 1.6 G / Chips ( Overclocked stably )

We in use with a MOD small router ( WiFi ), running OpenWRT, install Miner Software on it!  
Your BTC Pool acc, its to be set on GUI Browser !

Script are in Python, There is also a program to test Chips connection, when u got the delivery ~
it will show u which chips have bad contact ~

e.g. in Terminal ~ run

C:\>modular_ava2.py -s com3

etc

I can mark down, or label down ~ cable connectors ~
Right after testing completed, pior packaging~ in case of wrong connection!

3rd Patch  ( 18 - 19 Feb ) - Limited to 2T
      
160 G     $1,580
240G Overclock       $ 6 / G
      
320G      $2,680
480G Overclock      $5.6 / G

Included: -

1) Blade - Fully Assembled with Chips - Heatsink
2) FPGA Control Unit
3) Connection Boards + Connection Cables
4) For Great People ( included with a Xilinx FPGA Programmer, with adapter & cables )  

Not Included: -

1) Delivery Cost
2) Case  ( 320 G, 4 blade can fit in ATX case - its easy to MOD )
3) ATX Power supply ~ ( 160G system - 12V 28A ) ( 320G system - 12V 56A )


~Lead time is 5 - 7 days times ~


Each Blade is @ 80G --> 120G Overlocked ~  ( 80 Chips )


TT $USD to our company account is prefered !  
If your base currency is not USD, then pls send HKD$ ~ rate is $7.78

We can accept Paypal in HKD, rate is $7.78
Not recommended of 320G System, as the actual charge is too high ~
Paypal will charge u around 3% extra ~ ( ~ $80 USD ! )

( since we need faster return to order more part,
pre build in advance, to reduce the lead time! )


pls check our other post !

We're going to use it with the "Avalon 2 Reference Design" mostly !

Also the current design of "K16 Avalvon2
( Redesign by Form )",   great hardware & Very Compact

Yes,  we take Paypal ~

For > USD$2000 ,  TT may be cheaper !


Paypal account under our company name,  hopfully most of u would feel safer to do Group Buy ~

55nm gen2 Avalon chips,  Its all the reason they're here~  Its 1 - 1.5 / chip " A3255 " ~    110nm will not get pass 350 Mhz /chip " A3256" ~

Update~   Speed have pass 21 G Now   ~

Jeffrey

Currently, its already Passed 1G / chip ~  

as I'm getting 17.6 G average     Any news from guy ~  

Now work flawlessly with MinePeon ~ for Rasp. PI

0 Reject ~ 0 error

Special Thanks for Neil ~ who bring lots of us ~ To Joy of PI !! Pls support MinePeon !
It is so easy to use ~

MinePeon - SSH


MinePeon - Web Interface

if the Max Count is 8 ~  >>>>  #define TICK_TOTAL   20800

Try to adjust this will get u different result ~  currently Max I get is around 12 - 16 G~  unstable ~

1st - #define MAX_WORK_COUNT      8  // must be binary multiple and match driver

2nd - #define TICK_TOTAL          12355  // 2^18 / 21.33uS TMR0 period (adjusted down for push time)

3rd - #define DEFAULT_HASHCLOCK   2300

this are the combo ~ u need to try on vary no. ~ if u get a best Combo ~ pls suggest here too

Happy Great New Year ~  There is no other greater news than hear from u ~

Thanks for the MinePeon ~  Bring many ppl to get in the world of Pi ~   

Specially bringing alot of joy to ppl like me,  the joy is much greater than having BTC ~


Currently I'm trying to get it work with K16 Avalon2 - " Redesign by Form "
On windows / OSX , we current get to around 13 ish G ~  on BFgminer ( Target is 24G )   

 
https://bitcointalk.org/index.php?topic=323175.80~
You like to have a look  ~ The Hardward is great - I will evetually get to the 24 - 25.6 G
( just need to adjust some numbers in originally K16 Firmware ) Tick_Total / Work_Ticks are need to figure out ~

Neil, If you like one ~ I make u for $150 "U only" ( Fully Assembled with 16 avalon 2 Chips )

Seems to work,  I just need to try Patch CGminer for it..  ( It also use the MicroChip ~ PIC16LF4659 )
Form said that by using Bfgminer,  patch is not needed ~   
( So i guess,  When u fight down the Nanofury,  K16 Avalon2 will definitly work too on BFG )

Jeffrey

Cdragon,

I have been trying to do the compile on cgminer / bfg ~  but seem very hard to install all we needed~  Even with MinGW !

I have moved to try in Linux ~ seem more native this way ~

J

For ~   DEFAULT_HASHCLOCK  =  1000

We shoud have 16 Ghz ~  But still not the case here.

Below is needed to figure out :--


// set values for ASIC PLL, we use R=16 N=Freq in MHz

#define WORK_TICKS          16000   // 2^25 total / 2^18 hashes per tick   ( 2^25 ~ as the Crystal is 25Mhz ,  address me if I'm wrong ) 

#define TICK_TOTAL          20800   // 2^18 / 21.33uS TMR0 period (how do we find out if 21.33uS is right ? )


Hoping by more people joining ~ then we could figure this !   Maybe the about is piece of cake for U  ~~

  

It great to hear people are interested ~

i have plenty of chips ~

The design by Form is great ~  we just need to try different figure in the firmware, to Optimize the speed

I can offer u $250 for a whole Kit ( PCB, Chips, 12" Fan & HeatSink included ),  If u're interested to Join us

or $280 for Assembled ~

Fan ~ ( 12" Cool Master 2000rpm ) Sickle Flow X - High Airflow 90 CFM -


-------------------

I have work out value Price:-   Since price for power module ( we are already having 1000+ pricing ) & $7 - 8 /chips are pretty much fixed ~

Only thing is labour cost can go down alot in volume.

2 -  5+ pcs    ~ $245  USD
6 - 10   pcs    ~ $235
11-19  pcs     ~ $225
     20+ pcs    ~ $215

Form :  We need oscilloscope for the ~ TMR0 Time period (uS) ?

            also if ~  2^18 hashes per tick ,  still valid ?


Cdragon:  Nice Soldering ~ the board looks great ~ Nice slot

if that is still true on 16 chips board ?

hash unit working clock frequency = XCLKIN frequency * F/(R*(2^OD)).
