0a) What to Expect (top)
Bitmain's Antminer combines four BM1382 chips into a small package. Noise levels are extremely quiet and so can life on desktops and be given as gifts. A
USB cable and power supply is provided in the package, although you will need a power cable and external controller to get started.

Chips	4x Bitmain BM1382 Gen2
Hashrate	60GH
Rated Voltage	12V
Rated Current	4.5A
Power.Consumption	~55W

 

      
 
      


0b) What You Need (top)
In addition to a host windows PC, you will need some accessories to get started.


                             Click your flag to find everything you need to get started at Amazon!             
                    
                                         


1) Powering (top)
U3's come with a 2.5mm 6A 12V mains power adapter, although you will still need a mains power cable.

      


2) Cooling (top)
The U3 is self sufficient in cooling terms and  is self sufficient in cooling terms and utilises an aluminium finned heatsink on the top of the chips. A 92mm fan
provides ample but silent airflow through the heatsink and over the board. The backside of the PCB is screwed to a blue aluminium plate, which acts as a
heatsink and the base of the case.

      

      
 



3) Configuration (top)
U3s can be run on any CGMiner based device. A Windows based PC is recommended although a similar process can be applied on a Raspberry Pi.

Wiring:

• Plug in the USB cable from the U3 to your computer.
• Plug in the power supply into the mains.
• Plug in power supply into the U3.

Configuration:

• Download the latest version of CGMiner and Zadig.
• Extract, and run the zadig application.
• Select "CP21202 USB to UART Bridge Controller" and then click "Replace Driver". You only have to do this once per computer.
• Create a new file in notepad and enter pool information as below. Save it as a .bat in the same folder as CGMiner.
• Run the bat file to start mining.

Antpool

Code:

cgminer.exe -o stratum.antpool.com:3333 -u dogie_U3 -p 123

BTCGuild

Code:

cgminer.exe -o stratum.btcguild.com:3333 -u dogie_U3 -p 123

GHash IO

Code:

cgminer.exe -o us1.ghash.io:3333 -u dogie.U3 -p 123

4) Troubleshooting (top)
TBD as problems arise.

Is Bitmain still applying thermal paste with a pneumatic butter knife?

Is Bitmain still applying thermal paste with a pneumatic butter knife?

They're usually very good with thermal paste, if you see S1-S4 chip pics, they spend the time to paint each chip individually. I'm not sure what happened on this one, but it was impossible to clean with all the resistors so close. Was either going to be goop or cloth fibres, and the goop was there first.

I think the only other thing to try would have been something like a long nylon cleaning brush from an electric razor dipped in alcohol. Still tricky though.

any good recommendations on images for raspberry pi controllers to run these?

Annndddd...bookmarked. I just purchased an Antminer U3 to test the waters, this guide is comprehensive and easy to understand. I wish I could tip you.

You can, but its not required by any means!

[Slight necro, was accumulating U3 feedback from all the threads]. That's a good point, I'll find some micro brushes to buy. Can douse them in articlean and work out the paste.

Raspian, Minera, MinePeon, anything that will get you cgminer.

I am familiar with minera for Gridseed devices but was unable to get it to detect the U3 I was offering this as a suggestion for a future guide from you if you had time to put together a setup guide for Running the U3 off of the Pi to expand off this setup guide. I have also tinkered with Minera but the latest build has an outdated cgminer and wont detect the U3 and the bfgminer works but only hashes at 4GH. I am still tinkering but no clean off the shelf solution to run a Pi with the U3 yet without some tinkering

I still go for Raspian because its essentially just a linux environment, so you can put whatever cgminer you want on it. There are obscenely long instructions for that in the Noncetech guide if you want to go from scratch, although other users may be able to provide nearly complete SD card images for Raspbian.

after some tinkering i got minera to work with some ease. Minepeon is to outdated to work with the U3 out of the box for anyone else looking to run these on a pi go with Minera and change from default of CPU miner to CGMINER on the latest version 4.0.0 works with only those changes

So how quiet are these miners? (can not find any video with this miner) im only after quiet miners. i did see that Bitmain came out with a new design on them.

It looks to be exactly the same fan, so it then depends on what your definition of 'silent' is. To me they're as quiet as ambient, but its personal opinion.

These new ones should get a little more air because of the new design maybe run a little colder and fan speed may not need to be so high. its just a thought... 

[DebitMe]

I got a brand new U3 straight from Bitmain over amazon.  Have been fiddling with it all night and can't seem to get it recognized by CGminer.  I have done all the steps and don't know what else to do?  Any ideas would be helpful.

My zadig says the Driver loaded on "CP2102 USB to UART Bridge Controller" is WinUSB (v6.1.7600.16385)

I downloaded CGMiner 4.9.0 and made a notepad file with this in it...
cgminer.exe  -o us1.ghash.io:3333 -u DebitMe.U3 -p 123
and saved it as a .bat file in the cgminer folder.

My Devices and Printers folder shows the unit as "CP2102 USB to UART Bridge Controller"

When I start CGMiner it says "No Devices Detected"

What am I missing?  It seems to be recognized by my computer, but just not by CGMiner.
