Do you have any pictures of the actual board(s)?

How many can be chained together in an SPI chain? You say that any standard ATX PSU can be used, so does that mean they have PCIE power connectors or you have 6pin to barrel/12v adapters?

You can chain up to 6 together is 1 chain, each controller can power up to 24 boards total.
I have both the Green 4 pin power connectors, and PCIE>barrel adapters

Price drop to $75/board

[cannachris]

Cool. How much would shipping to mainland EU be?

[bobsag3]

Price drop to $60/board.

2.2 btc for 20 boards, does it include pi with controller and shipping to eu?

[btljuice]

So if 6 run in 1 SPI chain, can you run 6 of them with just a raspberry pi and no black arrow controller? Or is that controller needed for any setup? Also, power connectors. Do you include PCI-E to (multiple) barrel connector cables? If so, how many boards would 1 PCI-E plug power?

Yup thats exactly it.

Does  not include shipping, includes controller + pi

YOu need the pi and controller regardless of number. We will include the power connector for up to 3 boards per PCIE as long as your order 3 boards.

hey bob with the "g", lol

can you post more pics ? maybe some screenshot while hashing the pic posted here & BA link is different : dual fan vs 1 single bigger fan.

60USD/36gh/s (according to BA site) - approx. 1.67 usd per gh & there is a little note on the site (this is a used product) so is this batch new or used ?

a little details also pls, "up to 40gh/s" so what is the minimum @ stock settings i'd assume min is 30 gh/s ?

seems like it's a little over 1W/gh (stock no OC) if i'm not mistaken.

any warranty ?

what rate are you using if paid using btc ? accept paypal,credit card ?

OP says includes shipping, what kind of shipping ? dhl/fedex,etc ?

not trolling just want more info before i make up my mind to make a purchase.

thx.

I can get plenty of pics tomorrow.
These are the dual fan V1 boards.
Used (old batch) boards.
They average out to 36-37gh overall, some do 39-40, some do 34-35.
They use just about 1w/gh at the wall
7 Day DOA warranty
Coinbase Rate, I can take CC/Paypal at a pretty high (~10%) fee. Otherwise Wire/Cash Deposit into Wells fargo/Money Order
We ship UPS/USPS exclusively

Let me know if you have any other questions.

By controller you are referring to the raspberry pi. So to power the whole setup one would need 16 Pi units. Now, do these boards have some usb breakout connector or do they interface with the Pi only via the SPI connector. The issue is that since you have 6 per chain how do you tie together 4 chains together to be controlled by the Pi's single SPI connector?

No. You need both a Pi and A Controller, and a single Pi+controller combo can power ~20-24 boards. 4 stacks of 6

Ok, gotcha. Thanks for clearing that up for me.

Im confused, whats their stock rated speed  / power consumption?
Whats their OC potential / power consumption?
