Bitmain Antminer Asic Miner U2 USB 2 GH/s (overclockable up to 2.4 GH/s, for BitCoin [BTC] Mining: SHA256)
[ANTMINERU2USB]
Item #:  244

The Bitmain Antminer U2 is a USB Bitcoin (BTC) miner that hashes at 2 GH/s, but overclocks up to 2.4 GH/s, with heatsink. The miner is very power efficient, pulling only 2.95 watts. This is a great way to enter the bitcoin mining game. Plug it into a USB, run CGMiner or BFGMiner, and you're set!

Specifications:

  • For only Bitcoin mining
  • Icuras support SHA256 algorithm
  • 2014 model: v1.2 board
  • Default hash rate: 2 GH/s, can overclock by command up to 2.4 GH/s
  • Power consumption: 2.95 W on USB 5V @ 2G
  • Power supply: 5 V DC input (from USB)
  • Factory heatsink for stable operation
  • Size: 60 × 25 × 15 mm

How to use?

You can use with your computer / laptop (supported OS: Windows, Linux, Mac OS X) or direct with router (OpenWrt / DD-WRT).
Required driver: CP210x USB
Plug in your Antniner U2 to a USB port on your computer / laptop / router.
Start mining software:

cgminer.exe --bmsc-options 115200:20 -o pool_url:pool_port -u worker_name -p worker_password --bmsc-freq 0981
bfgminer.exe -o pool_url:pool_port -u worker_name -p worker_password -S antminer:all --set-device antminer:clock=x0981

To overclock your Antniner U1, you will change that last part of the running parameter. The number following bmsc-freq and antminer:clock=x will change:

  • for 2.0 GH/s use 0981 (default)
  • for 2.1 GH/s use 0A01
  • for 2.2 GH/s use 0A81
  • for 2.3 GH/s use 0B01
  • for 2.4 GH/s use 0B81

Keep in mind that the Antminer gets very hot very quickly when you overclock. Your must add additional cooling to your device. I recommend a strong fan blowing cool air directly onto your Antminer U2!
