Sold out in 3 minutes!
I managed to put 10 into my basket. While I prepared the payment, shop-system told me "out of stock". Not sure about those 10. They should be reserved while I try to pay the invoice. I hope to be one of the Lucky Guys.

I got some from ASICPuppy. Theirs were slightly cheaper -- without the 0.97 -- but shipping was a little more. Either way, I got some. M |
I mine at Kano's Pool because it pays the best and is completely transparent! Come join me! |

Bought 10. But how thick is it? In other words how many USB hubs will this take?

EUR 64 + shipping huh. That's $80 a pop.
That's a year to break even at current difficulty levels.
Think long and hard, guys.
What better product is there? (the OP says they are even more efficient than Bitmain) EDIT: I understand ROI vs difficulty and these are not in one's control (can't keep more people from coming on board). The difficulty will increase in when all these USBs hit the market but I expect the opposite as the older versions become less and less profitable the owners will pull the plug. |

Do we know the outer dimensions yet? length, width, circumference, outer diameter? I need to develop some sort of rack to hold a few in place for airflow while using extended cables for the hub.

Your second link does not work (page not found) but the OP is shipping the devices with a USB 2.0 connector so even if your hub is 3.0, the miners will not have the additional pins to the USB 3.0-specific protocol. But the 3.0 only if you want future proofing but I would recommend getting the USB 2.0. Actually you WANT a 3.0 hub, since these hubs are usually rated for 1+ Amps. Even though the miner does not use 3.0 data speeds, it does pull alot of power for USB obviously, so a 2.0 hub might not provide enough power. |

Demensions are very similar to original moonlander Width: 25mm, Length: 58mm, Hight with heatsink will be about 20-30mm (still finalizing heatsink design for these). Components on other side of PCB stick out another 5mm or so. |

Even though the miner does not use 3.0 data speeds, it does pull alot of power for USB obviously, so a 2.0 hub might not provide enough power. Thank you for the clarification, I deleted my message to avoid confusion but can you please clarify/recommend what to use to get the maximym power? From what I gathered in the OP @ 1.5W per MH/s: | Hashing Speed | Power | | Amps | | 2 MH/s | 2 x 1.5 W = 3 W | | 3 W / 5V = 0.6 A | | 3 MH/s | 3 x 1.5 W = 4.5 W | | 4.5 W / 5V = 0.9 A | | 5 MH/s | 5 x 1.5 W = 7.5 W | | 7.5 W / 5V = 1.5 A | | 6 MH/s | 6 x 1.5 W = 9 W | | 9 W / 5V = 1.8 A |
It seems that a normal USB 3.0 with 900 mA can only drive the unit at 3 MH/s steady state, anything above that will need a powered USB hub as "Y" cables don't work in USBs. The hub in the amazon link was 7 ports 60 W = 8.5 W per port so it can drive the unit up to theoretical speed 8.5 / 1.5 = 5.7 MHs Is this correct? Question 2In your demo screen the title bar states ... "ethminer" can these sticks be used for anything other than scrypt? |

USB 3.0 spec is for a max of 900 ma (0.9 amps) of 5V supply - there are variant "charging" USB 3 ports that are designed for higher though, but not all motherboards have them and not all that DO have them have all of the ports as "charging" capable.
Powered hubs would be a better option.
On a separate subject, is there any chance of a "pod" or "blade" version of this, along the lines of the old Gridseed GC3344 based units?

For example at about 3MH its 1.3w/MH, but at 5 MH it approaches 2w/MH. The 6MH is also not sustainable long term...that was me just showing how far the hardware can be pushed. Ethminer is just the hostname of one of my dev systems (that also happens to mine ethereum with its GPU). Has nothing to do with this stick and it can only mine scrypt coins. |

I have to ship out all these sticks you guys ordered first  Definitely stay tuned though...this pre-order was massive success and wont be stopping here  |
