It's composed by ASIC?

Basic components ASIC miners:

     ASIC chips: Device core. These chips are designed specifically for mining and can perform  calculations

     much faster than conventional computer chips.

     Control board: Controls the activity ASIC chips and ensure their communication with the outside world.

     Power source: Supplies the necessary energy to the device.

     Fans and cooling: Due to the high thermal output ASIC of chips must be effective

     the cooling system.

     Cabinet: Protects the miner's components from external influences and helps with effective cooling.

     Connectors and interfaces: E.g. Ethernet ports for connecting to the Internet.

      Each model and manufacturer may have a different configuration and design.
