We are opening sales of 4-chips bitfury ASIC miners. Available in stock, shipping starts this monday 4 of november There are two versions of the same product. The first one is a fully assembled PCB board with 4 chips ready to use, which is meant for more experienced users who already got raspberry pi and know how to set it up. The price is 1.09btc - http://bit.ly/1h2BrxpThe second one is a plug & play "starter kit" which is meant for all types of users. This kit includes 1 board, raspberry pi, power supply and all required connection wires. The raspberry pi includes the latest configured image. Just plug and mine. The price is 1.47btc - http://bit.ly/18FhfHOThe boards are designed in a way that it's really easy to connect them into the chain, so in the case you would like to get more powerful miner you just need order few items and then connect them. The board includes an external 40A regulator. You can easily change the voltage. Any single miner would achieve 11 gh/s @0.84V and even more with overclock or higher voltages. There are two types of shipping available, 24h express shipping and standard shipping. Not included in price |

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I hope the after-sales support of this board will be better than the support I'm waiting to receive, after having bought and received the bitfury kit more than 1 week ago, with wrong power supply (5V @ 0,5A instead 12V @ 2A). I even can't get any info about what files / variables I need to modify before recompiling cgminer and getting a little more than the 1,96 GH/s I get from the Bitfury.

Looks great!
I just had 4 bitfury chips stolen from me!
Do you have anything similar for avalon chips?

What's the deal with voltage regulators? Do you still have external ones to power several boards?
Does the fully assembled board include the regulator?

The boards include the voltage regulator module, pre adjusted to 0.84V. It's very easy to connect, just 4 wires into terminal blocks.
The voltage regulator modules can drive up to 40A. (3 boards with overclock margin).

So I can order 3 PCBs (without the chips) + 1 regulator module, right? How do I do that, order 2 PCBs without the regulator and 1 with? Also, what about shipping to Ukraine? Sorry, but we don't have the shipping price to your country.
Do you subtract VAT from the price when shipping outside EU? What exactly are the shipping services you use? |

We've updated the shipping database. We offer ups express saver shipping (24h) or TNT europe (3 days).
To order, just order two pcb without the regulator and one with. The regulator is 40A so can drive up to 3 boards.

Great! Is the variable resistor included? If not, which range of resistance is needed?
Also, how do I terminate the bus? Green must be connected to ground through 1kOhm, right?

We include in your parcel 2 resistors for 0'87-0'9V aprox. The range will be 4'5k to 3k(1V) Formula is Resistor=1200/Vout-0.6 Be aware the wire measure from regulator to board, in the pcb terminals will be less voltage. We test the chain with final resistor and without and we did not find changes. Regards |

Hello again! I received my boards on Saturday. Then it took me 5 nights (including 3 reflows of the chip) to get my first chip working:  I am waiting for discount on my next purchase. |

Is there updated prices for these due to the climb in value of BTC?

Looks like prices on their site change automatically with BTC/EUR rate. |

Will it be possible to buy a PCB from the new batch without chips and power circuit, to it use with an external voltage converter, like previous board generation? That was really simple and cost-effective solution for DIY.
Also, please check email.
