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.

BobSag3 , are you currently selling these in less than 500 batches. I saw these through the antminer s1 post and just wondering what price your going for. At cost these things are are cheaper than the u1 with the added potential speed boost. Add me to the list to inform when you get them ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) . At least I know your local.

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 ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

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 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?

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.

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. ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs28.postimg.org%2Fvf0afw6q5%2F20140220_202136.jpg&t=665&c=IgG7Hs1tH_O_1g)

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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

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 15 BTC to invest it would be on other things ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)
