Hi Guys
We will have a couple of working prototypes by this Wednesday , if everything goes as planned we will put it into mass production , il keep you guys updated on this thread.
We will be offering completed boards and DYI kit's based upon form's design. We'r launching our website soon.

Bit-Tech, were you able to source chips as well or are these going to be blank boards? We will have a couple of working prototypes by this Wednesday , if everything goes as planned we will put it into mass production , il keep you guys updated on this thread.

At december 8th i will make a summary, get prices at the distributors, pcb-fab and assy and will reply to your mails with an offer you can't refuse 
Hey,
sorry for being a bit late with my answer. Many people were asking me how much these boards will cost, and how long it takes, etc.
I was collecting the ammount of boards to get specific prices for boards and assembly - But here in germany the prices are way too high.
Meanwhile the user "bit-tech" flew to Shenzen in china to check the prices there and he got it managed to get really good quotes there.
And this is where i'm out of the game now:
bit-tech is now ordering a big amount of boards & chips and getting them assembled there. He will post here in the next days with more details.
Please Please PLEASE make a single or double chip USB miner
It'll be way too HOTMake a single or double chip USB coffee warmer.

Shame nobody plans to build Avalon batc 1,2,and 3 compatible board but with 55nm chips.
I agree. I have a working mini backplane that turns 2 Avalon hash units into a 20 chip Klondike.

Just another card design
We are putting this up as another entry in the contest. All design materials will be made available to the public if we win Avalon's contest.
Features
We are putting this up as another entry in the contest. All design materials will be made available to the public if we win Avalon's contest.
Features
- Converts Gen2's CONFIG and REPORT signals into high-speed SPI protocol for direct connection to SPI pins of on-board PIC32 Microcontroller.
- Power supply voltage is software-adjustable from 0.9V to 1.1V, in 64 steps. We used the LM10011 from TI for this.
- Card has on-board USB controller, available through the PIC32MX chip.
- Uses PIC32MX microcontroller, which has on-chip SPI and USB peripherals.
- Uses only high slew-rate SN74LVC glue logic.
- Compatible with either BFGMiner or CGMiner.
- Temperature monitoring using the PIC32MX on-chip thermometer.
- Uses a 25.000MHz oscillator module (instead of a crystal and low slew-rate logic used in ref design) for more reliable operation.
- Same form-factor as original Gen1 hash card so that the same heat-sink can be used.
Hey guys...
I finished a 16-chip board design.
Size: 145 mm x 70 mm (5.70866 inch x 2.75591 inch)
Board features:
cgminer/bfgminer patch features:
Support:
The best way to get support at the moment is joining #avalon2 on freenode IRC
Get a board:
I can offer bare pcb's and ready-to-mine units. But first i have to see how much demand here is, to get an idea of how many boards i should order - which is turning the screw of pricing.
If you want to order a board, send me a message with the following information:
At december 8th i will make a summary, get prices at the distributors, pcb-fab and assy and will reply to your mails with an offer you can't refuse
Be aware that i don't sell Avalon chips. If you want an assembled board, you have to supply the chips on tape or reel to me in germany.

I finished a 16-chip board design.
Size: 145 mm x 70 mm (5.70866 inch x 2.75591 inch)
Board features:
- Very efficient (~90%) DC/DC converter to power the ASICs
- Adjustable voltage (0.85 - 1.25 V) to choose between efficiency and overclocking
- USB-Interface to connect to a host running cgminer or bfgminer
- I²C interface to chain multiple boards together
- 100% flat surface on the bottom side to mount a usual heatsink
- On-board temperature management
- Fan connector with rotation speed measurement and PWM-control
- Indicator LED to report USB-activity
- 4-layer PCB for optimal heat/current transportation
- Two board designs available: one for 10 and another for 16 ASICs
cgminer/bfgminer patch features:
- Reporting temperature, real ASIC frequency and fan-speed back to the host
- Control of ASIC frequency in a big range from 62.5 to 5000 MHz in smallest possible steps
- Control of a desired temperature

140GH/s 494watt @ 120v
All things considered, that is not very good for a Gen2 :/
Not very good at all considering that for that power consumption you can have 500+ GH with bitfury chips.
What I wish someone would do is build a clone of the Avalon blade but with bitfury chips. Naturally there would be considerable technical challenges with this (such as the fact that bitfury chips use a SPI bus, etc) but it would be a shame to waste the avalon chassis.
you could easily run 10 Fury boards HEX16B with single tplink giving you 450 GH.
True enough, but the idea is to be able to mount them _inside_ the avalon case. I wonder if one could string some of these HEX16B boards in a row (horizontally and essentially laid on its side so the heatsink is facing the flow of the avalon fan). Or just make a stack and turn it sideways and mount several stacks inside the avalon case.

2 hour results.
Seems one of the systems rebooted 1 hour 40 mins in.

I received the two Gen 2 Mini Units today.
Ordered Thursday 14th. Waybill emailed and texted Friday the 15th and took delivery of units today November 18th 2013.
They two systems were simple to setup and pull 495 watts @ 120v.
Just below 140 GH/s performance.
The packaging was excellent and more than adequate.
I will give 1 hour and 1 day stat results.

Would love to see Gen2 boards being released for fitting into an Avalon Mini. This would make me super happy... Or just someone picking this up and running with it.
Ngzhang, are you guys going to produce your own modules, or are you going to abandon the backwards compatibility idea?
We will release a few (very few) Avalon Gen2 Mini prototype on our shop in 1-2 days, this prototype will NOT mass production.

(not put up yet)
It's basically based on our open-sourced design, 96 chips running at 1V/1.5GH, 144G overall speed. most of the parts are the same with Gen1 mini.
I think this is a start, it's easy to build upgrade modules for Gen1 machines.
But we will NOT produce compatible modules our self in large number, a lot of people can do it faster I think.
I see in your shop 5.5 Bitcoin for a 4 module miner, what drugs are you taking?
