Description

In May 2019, MicroBt launched their well known Whatsminer M20 series. Whatsminer is MicroBt's Bitcoin mining hardware brand with an ASIC Plug & Play Mining design sold by MicroBt. The Whatsminer M21s mines Bitcoin(BTC) or Bitcoin Cash(BCH) immediately and helps miners jump into the new digital currency rush.

Seen as the ultimate win-win, successful reproduction of the earlier models of the Whatsminer M10 series, the products consisted of the M20, M21, M21b, M20s, and M21s, all adopting Samsung 8nm chip, and releasing MicroBt’s new logo, which has more features and is more characteristic.

Founded in 2016, Shenzhen Bit Microelectronics Technology (Also Known as MicroBt) is one of the leading Application Specific Integrated Circuit (ASIC) producers. The company is into the production and design of high-end 28nm/16nm/7nm working chips and provides developments/assistance in fields such as blockchain technology, cloud computing, and artificial intelligence.

Specifications


The hash rate of the Whatsminer M21S is 56T, which gives it an edge over the M21 model, and the physical size is 155 x 240 x 390mm with a weight of 7.1kg. The size dimension makes the device less bulky to handle and also helps conserve space in mining farms. 

The M21s come with a P5-12-2200-V1 power supply to produce an output of DC 12.8V 172A, and the 10A socket in the mining farm works well. 
The power supply comes with an aluminum rack, which protects the wires on the connector side. It is used as a handle for ease of usage.
This miner works with a power efficiency of 0.06j/Gh, and it has two 12038 cooling fans, one for blowing air and one for release of air, and the fan power is 12V 2.8A, just like its older model.

Algorithm

The Whatsminer M21s mines with the SHA-256 algorithm can produce up to 40 coins, but the top coins are Bitcoin(BTC) and Bitcoin Cash(BCH). With an average hash rate of 56Th/s, it uses 3360W of power. 


The board is an Ethernet interface, TF card slot, IP button, reset button, and status indicator on the control. But the most impressive is the fact that the MAC address is attached to the control board for convenience when looking for the device's IP address. This feature aligns with Whatsminer’s pledge to produce miners that are easy to use for everyone. 

Noise Level


This device's noise is pretty normal, as most miners have a 60-80dB noise level. To better understand this, a noise level of 75 dB is equivalent to a vacuum cleaner's noise emission. The Whatsminer M21s can be used for mining at home as the noise level is optimal, but mining farms are more suitable. The noise is normal as a result of the two fans set for cooling.
