Antminer S21++

Custom firmware unlocking fine-grained power control, auto-tuning and lower pool fees. The built-in DPS (Dynamic Power Scaling) mode self-regulates the miner's wattage in real time based on conditions — more Bitcoin per kilowatt-hour.

BraiinsOS+ is optional — we install and configure it as a service if you want it on your machine. Note: altering the OS breaks the manufacturer's warranty. A Braiins license is required to install the OS on some machines — we'll flag that when you order.

Pair the miner with Hive_Control to unlock smart home integration. Heatmode ramps the miner up or down to maintain a target room temperature — like a Bitcoin-mining thermostat. Schedule mining to run only when electricity is cheap, when solar is producing, or only between certain hours of the day.
