The home mining hardware market ranges from low-power open-source devices you can run on your desk to industrial machines that require a dedicated room and three-phase power. Here's how to navigate it.
The Bitaxe Lineup (Our Recommendation)
The Bitaxe is the flagship open-source Bitcoin miner. Designed by the OSMU (Open Source Miners United) community, every Bitaxe variant is fully open source, hardware designs, firmware, and software are all publicly available on GitHub. No proprietary firmware. No black box.
All Bitaxe models run AxeOS: a browser-based dashboard for configuration, monitoring, and firmware updates. Plug it in, connect to WiFi, point it at a pool, and it's mining within minutes.
Current Models
Hash rate: ~1.2 TH/s
Power: ~15W | Efficiency: ~12.5 J/TH
Best for: primary home miner, best performance per watt in the lineup
Hash rate: ~1.0 TH/s
Power: ~14W
Best for: solid performer, proven reliability
Hash rate: ~500 GH/s
Power: ~5W
Best for: ultra-low power, first Bitaxe, minimal running cost
The Bitaxe Evolution
The Bitaxe project has progressed through several generations, each improving efficiency as newer Bitmain chips became available to the open-source community. The lineage: Bitaxe 100 (BM1397) → 200 series (BM1366) → 300 series (BM1368) → 400/600 series (BM1370). The community actively maintains AxeOS firmware across all models, older Bitaxes continue to receive updates and support.
The OSMU Discord and GitHub are the authoritative sources for the latest variant details, efficiency benchmarks, and community-tuned configurations.
Beyond the Bitaxe: Community Variants
The open-source ethos has inspired a growing family of community-designed devices. The NerdAxe applies the same open-source approach in a different form factor. The NerdOctAxe takes it further, chaining multiple ASIC chips for higher combined hash rates. New variants continue to emerge as community members experiment with newer chips, different board layouts, and novel cooling solutions.
We can't list them all here as the landscape evolves quickly. For the most current picture of what's available and what the community is building next, check the OSMU Discord and GitHub directly.

Non-Open-Source Alternatives (Honest Acknowledgement)
We sell Bitaxes and believe in open-source hardware. But we also believe in honest information. There are other home-friendly miners worth knowing about.
Antminer S21 Home (Bitmain / Braiins)
Bitmain, in partnership with Braiins, has produced a home-oriented version of their industrial S21 series. Higher hash rate than any Bitaxe, but significantly louder, more expensive, and runs proprietary firmware. Not open source.
Avalon Nano Series (Canaan)
Canaan's Avalon Nano line is a compact, low-wattage miner aimed at home use. Quiet and approachable. Also closed source. Canaan has historically been more receptive to the home mining community than Bitmain.
What to Avoid
- Cloud mining contracts: Paying a company to mine on your behalf. Historically associated with scams and poor returns.
- USB "miners": Small USB devices claiming to mine Bitcoin. At the hash rates they produce, they're novelty items.
- Second-hand industrial ASICs without proper electrical setup: A used Antminer S19 draws 3,000W+. Without appropriate wiring, ventilation, and circuit capacity, this is a fire hazard.
Summary
For most people: start with a Bitaxe Gamma 601. Best performing open-source home miner currently available, quiet, ~$3/month in electricity, genuine participation in the Bitcoin network. All of our setup documentation is written around it.
