Avalon Miner 821 (A8)

The AvalonMiner 821 is the ROQ Solid Miner, Refined. The AvalonMiner 8xx is made with Reliable Open Quality, now with Airforming Cooling Technology.

Containing 104 x A3210 16 nm chips, AvalonMiner 821 is the latest Canaan AvalonMiner with a 11.0 Reliable Hashrate Per Second (RTHS).

By connecting our AvalonMiner Controller (sold separately) to a single AUC3 (AvalonMiner USB Convertor 3), you may connect five AvalonMiners. For maximum usage, you may connect the AvalonMiner Controller to 4 AUC3 devices which may each connect to 5 AvalonMiners for a total simultaneous management of twenty AvalonMiner 821 to reach 220 TH/s (RTHS).

If you manage a large installation of AvalonMiners, we can help you to deploy our openly developed AvalonMiner Management System which enables you to efficiently manage thousands of AvalonMiner machines.
