The Whatsminer M30S++ miner produces the following coins: Bitcoin, Bitcoin Cash, Crown, Litecoin Cash, Auroracoin and other cryptocurrencies (about 20 in total). The device runs on a 7nm processor from Samsung, which is practically no different in productivity from the BM1397.
The ASIC has an aluminum alloy body that is resistant to high temperatures and mechanical stress. The cooling system consists of two parallel fans. During operation of the device, coolers effectively remove heat from the case, thereby increasing the wear resistance of working units.
