Bitcoin mining machine Antminer U3 installation tutorial

The Bitcoin Antminer U3 is the third USB Bitcoin miner released by Bitmain, which is only priced at RMB 155, including shipping. The Antminer U3 started to be developed in July 2014, but was shelved for a while due to some reasons. This miner is very small and quiet, and the price is far lower than the production cost. It can be used as a decoration at the desk of miners, and the mining speed can reach 63G. Such a cool device plus such a good price will definitely be sought after by miners and Bitmain fans.

Unlike the previous Antminer U1 and Antminer U2, this miner does not adopt the previous USB flash drive shape because the difficulty of Bitcoin mining has greatly increased, and it is difficult for USB flash drive single-chip miners to submit share data. This miner uses 4 BM1382 chips and comes with a power adapter, which greatly facilitates miners to use.

Unboxing picture, the box design is very high-end.

After opening the box, there is a black shockproof foam covering the miner. Remove the shockproof foam to see the Antminer U3 and accessories.

All photos of the Antminer U3 and accessories, including a USB cable and a 72W power adapter. Because the power cord standards in different countries are different, my model does not come with a 220V power cord. After communicating with the company's production department, the officially released mining machine comes with a 220V national standard power cord, eliminating the trouble of purchasing it yourself.
