Check the area around U5 - that's where most of the changes are.

Well done, Steve! There is, in fact, a difference. I'm interested to get my hands on few.

Beside the heatsink they look like the u1. can not see any improvement.
They will be overclock able out of the box- no need for changing any resistors.
Based on the picture, can you tell what is significantly different between the two models?

wow, 0.0278 BTC / unit is a really great price.
yep, we need a EU group buy

the price went down because EUR/BTC went up
It is also 15BTC for 500 units.
Down to 13.9 now. I don't understand the purpose of these USB miners.
They will never make ROI, plus don't they have to be controlled by a computer?
And how much power does that consume?

in fact, this is the only unit i have owned that make ROI.. not in mining, trading the hardware. selling these units was a great deal

I have actually heard from a lot of people making good money by selling USB miners.
I personally don't think it is a good move for me.
If I had 15BTC to invest it would be on other things

This is my setup, Raspberry pi B + usb erupter.
Raspberry pi only uses 3,5W and can be charged with a common phone charger.
Install minepeon which is super easy to use.
Not making any profit with mining unfortunattely, so I started selling mining contracts on ebay.(24Hour mining)
That was making me a few cents a day but with a more advanced rig you could make some real bucks.

Depends on the computer. My tinker toy is a 60w headless xubuntu nettop.
BBB or raspi draw next to nothing.
Power hungry PCs are being replaced in many segments of tech, not just mining.
ROI - not beating that dead horse today.

Does it fit to asicminer 49-port hub?
Does the actual board look shorter to anyone else? Or is it just me..Looks like it got shorter and fatter with the new heat sink.
I think it's just you. Comparing the two, there have been some component changes (moved around/added, check the area around U5), but the overall dimensions appear to be the same.

i dont understand why they add this heatsink, i have 50 U1 and heat is not a problem at all
Because the U2 is intended to be overclockable out-of-the-box via software control. Naturally, people will be trying this and, knowing nothing of how heat transfer works, would be running into issues with them overheating with the U1's thin plate heatsink. I suspect you could still make the U2 overheat, too, anyway.I figure if you've got 50 in one of those bulky USB hubs, a custom cooling solution is probably not out of reach if the physical dimensions throw a spanner into the operation. Or just get another hub
running 1.95 ghs on each, 10 pcs in each hub and 2 fans..
in my country i also get free cooling from outside..
my basement is always cold, even with 50 antminers in the room. i dont understand why they add this heatsink, i have 50 U1 and heat is not a problem at all

The U1's are overclockable too....
Do you mean to say the voltages...etc... will be easily changeable via software? That would be fucking awesome!
As far as I have been told- yup.
As the listing says: "Default hash rate: 1.6 GH/s, over clock by command"
