Bitmain are committed to furthering the decentralization of the bitcoin network and providing quality products to consumers. In light of this, Bitmain is proud to announce its latest miner, the U3 USB miner.

The U3 utilises 4 of Bitmain’s latest generation BM1382 chips in high quality, domed case.

Batch 1 will go on sale on Oct. 18th Beijing (UTC +8 Time Zone). The 1st Batch of U3s are priced at 56 USD per unit (excluding shipping), with dispatch estimated Nov. 5th. A minimum order quantity of 60 is required, each extra units added must be the integral multiples of 20.

Specifications:

* Hash Rate: 63 GH/s at 0.75V
* Power Efficiency: 0.8 Watt/GH/s on wall at 0.75V
* Voltage: DC 12V input, 6A
* Chip Quantity per unit: 4
* One 80mm fan
* Noise: ~25 DB at 25 °C ambient temperature
* Hashrate and VDD core voltage can be adjusted via cgminer command line
* USB connection
* 12V AC/DC power brick of 16A, but power line not included
* Certificate Compliance: FCC/CE

Note:

1)   Power consumption: Quoted figures depend on your PSUs efficiency, the ambient temperature and the accuracy of the power meter.
2)   PSU: You must provide your own ATX PSU with 1 PCI-e connector, or a power line.

Features:

Scalable: Multiple U3 miners can be maintained by one controller running cgminer due to its USB port.

Hassle free: Setup consists of plugging in the USB and power cables and running Antminer CGMiner.

Cool: U3s remain cool and quiet due to its 80mm fan which quietly exhausts air out the side of the case.  

Stable and Accurate: Based on the tried and tested BM1382 chip, the U3 is extremely stable and is able to run 24 hours a day without problems.

Exquisite: The refined design of the U3 allow it to blend on any desk or shelf without standing out.

Liquid Cooled Miner C1: It is not only cool, but it is cool

The density of miners is becoming more and more important as the rapid growth of the bitcoin hash rate continues. The industry is trending towards industrial level mining, which leaves home miners without much choice for compact and quiet miners.

In response to this problem, Bitmain has developed a solution. The high end PC industry has used water cooling for years, and this expertise has been transferred to mining equipment. Bitmain is proud to announce our first Liquid Cooled Miner – the C1.

The 1st Batch of C1s are priced at 1 BTC per unit (excluding shipping), with dispatch estimated Oct. 25th

Specifications:

* Hash Rate: 1,008 GH/s guaranteed
* Power Efficiency: 0.8 Watt/GH/s at the wall
* Voltage: DC 12V input, 70A recommended, no PSU
* Water cooling block’s interface: G1/4-8 thread screw
* One 14038 Fan working with water cooling block
* Temperature: 38~40 °C at 25 °C ambient temperature
* Noise: 40~45 DB at 25 °C ambient temperature
* Ethernet connection, Stand alone
* Certificate Compliance: FCC/CE

Note: Bellow parts are not included in C1.

* Water cooling pump: Flow 450L/H, Head Pressure 3.0m, DC12V/0.5A, G1/4-8 screw threads, 1 unit
* Radiator: Aluminum, 389mm * 128mm * 36mm, G1/4-8 screw threads, 1 unit
* Fan 12025: DC12V/1A, including grills, 3 units
* Transparent tubing (ID/OD): 5/16” / 3/8” (10/8mm), 3 meters
* Coolant: If you choose an aluminum radiator, you can use deionized water with an additive, or specialist coolant. If you buy a copper radiator, you must only use specialist coolant.
* Connectors: G1/4” thread 10/8mm fittings to connect the C1 to the pump and radiator. Either compression fittings or barbs 4 units
* Spring clamps or worm drive fittings if you chose barbs, 6 units

Note:

1)   Power consumption: Quoted figures depend on your PSUs efficiency, the ambient temperature and the accuracy of the power meter.
2)   PSU: You must provide your own ATX PSU. There are 4 PCI-e connectors for +12V DC input and all are required.

Features:

Stand alone: C1 mines are stand alone and do not require a proxy server or external controller. Setup consists of installing the water pump, radiator, filling the coolant, connecting a PSU and an Ethernet cable.

Cool: Skving technology is used to design New-Style water cooling block. This allows for a large heat-transfer area, which keeps the PCBs exceptionally cool.

Quiet: Four hashing PCBs with 16 BM1382 chips per board are mounted to the both sides of two aluminum water cooling blocks, which are 250mm-long, 115mm-high and 13mm-thick. Each water cooling block contains 24 water channels for efficient heat transfer. A quiet fan works in tandem with the water cooling blocks in order to keep other board components on the C1 cool.

Stable and Accurate: Customized and optimized from the design of the S3+, the C1 is designed with the same PCBs and is supported by Serious-Double-Block Liquid Cooling technology. This allows C1s to benefit from the stability and accuracy of S3+ required to run 24 hours a day with minimal downtime.

Exquisiteie Casting Forming technology integrates the common heatsink with a water cooling block, compacts two water cooling blocks working in tandem. These technologies are saving space and allow for 1TH/s of power in a case the same as the S3.
