Braiins Mini Miner BMM‑101 Review
The Braiins Mini Miner BMM‑101 is a compact, desk‑friendly SHA‑256 miner built by the team behind the Braiins OS / Slush Pool ecosystem. It targets ~1 TH/s at ~35–40 W, with a tidy enclosure, on‑device screen, and close integration with Braiins tools. Think of it as a quiet desk companion for learning, sats‑stacking, and experimenting with modern pool features.
Pros:
- Desk‑friendly: ~1 TH/s at ~35–40 W; appropriate for 24/7 home use.
- Braiins ecosystem: smooth pairing with Braiins OS+ features and Slush Pool.
- Clean UX: compact case, small display, simple web interface for configuration.
- Stable networking: Ethernet (RJ45) for low stale shares.
Cons:
- Not profit‑oriented: 1 TH/s is hobby‑grade; solo is lottery‑style.
- Noise: ~40 dB typical—quiet, but not silent in a bedroom at night.
- Kit variance: some bundles ship without PSU; verify voltage/connector before ordering.
The BMM‑101 is for users who prefer a ready‑made mini miner with a polished UX and first‑party support. If you’d rather hack and overclock, compare with the Bitaxe Gamma. If you want plug‑and‑play mini‑heater + miner comfort, see the Avalon Nano 3S.
Key Takeaways
- Power‑sipping: ~35–40 W at the wall; easy on circuits, low heat.
- Solid efficiency for its class: ~35–40 J/TH (example math: 40 W / 1 TH/s).
- Home‑friendly noise: ~40 dB (A‑weighted) — like a quiet office.
- Ethernet‑first stability: fewer stale shares vs weak Wi‑Fi.
- Braiins tooling: integrates with OS+/Pool dashboards for clean stats and alerts.
Technical Specifications
| Item | Spec |
|---|---|
| Algorithm | SHA‑256 (BTC, BCH, etc.) |
| Hashrate (typical) | ~1 TH/s |
| Power (typical) | ~35–40 W @ wall |
| Efficiency (math) | ~35–40 J/TH |
| Noise (typical) | ~40 dB (decibel) |
| Networking | Ethernet (RJ45); web interface |
| Display | Small front status screen (varies by firmware) |
| Power input | External DC PSU (check kit; many are 12 V class) — see power supply basics |
| Dimensions / Weight | Compact desktop enclosure (varies by batch) |
Plain‑English examples: 1 TH/s means one trillion SHA‑256 guesses per second. 40 W is like a bright desk lamp. 40 dB is a soft office noise level—usually fine for a living room or home office.
Performance, Noise & Heat
Expect the BMM‑101 to stabilize near ~1 TH/s within minutes of start‑up. Wall‑power typically sits around ~35–40 W depending on your PSU and local mains quality. Noise stays near ~40 dB in a normal room—an audible but gentle whoosh; placement on a hard surface and open exhaust path helps minimize tonal resonance.
Heat output (rule‑of‑thumb): 1 W ≈ 3.412 BTU/h → 40 W ≈ 136 BTU/h — a warm puff, not a heater. If you want meaningful heat, compare with Avalon Nano 3S (140 W).
Electricity cost examples (24 h, continuous):
- €0.10/kWh →
€0.10/day (€3.0/month) - €0.20/kWh →
€0.19/day (€5.8/month) - €0.30/kWh →
€0.29/day (€8.7/month)
Formula: kWh = (Watts ÷ 1000) × hours. See kilowatt‑hour for a primer.
Setup & Pooling (quick start)
- Unbox & place: keep the rear exhaust clear; avoid cabinets or fabric surfaces.
- Ethernet first: connect RJ45 to your router/switch for stable shares. If you must use Wi‑Fi, consider an Ethernet bridge.
- Power: verify DC jack and voltage (many kits are 12 V class, ≥ 4–5 A). Use a short, thick cable to reduce voltage drop.
- Web interface: open the device IP in your browser, set pool URL, wallet address, and worker. Example pool string:
stratum+tcp://pool.example.com:3333
Username:bc1q...youraddress.worker1(Bech32 format)
Password:x(or as required). - Verify: after 5–10 minutes, hashrate stabilizes. Watch Rejected/Stale; if they rise, check network and pool latency. Learn more about the Stratum mining protocol.
- Safety: continuous load device—use good cords/outlets. Keep dust away from vents; clean periodically.
Easier with Braiins tooling: manage and monitor via Braiins OS+ dashboards and your Braiins Pool account. Their docs cover tuning and alerts.
Who Should Buy the Braiins BMM‑101?
- Beginners who want a neat, full‑stack experience (miner + pool + tools).
- Tinkerers who prefer a ready case with on‑device display rather than bare‑board DIY.
- Apartment users who need low noise/power and Ethernet stability.
Skip it if you need higher TH/s or heater‑level warmth; look at Avalon Nano 3S for heat or Heatbit Trio for a heater‑first design.

Verdict
BMM‑101 packs a tidy enclosure, Ethernet stability, and smooth Braiins integrations into a true home miner. Treat it as a quiet, low‑power, 1 TH/s desk unit for learning and sats‑stacking—not an ROI machine. If you value polish and a minimal‑fuss setup over open‑ended tinkering, it’s an excellent pick.

FAQ's
Is BMM‑101 profitable?
Generally no at residential tariffs; it’s about learning, sats, and low‑impact running.
How loud is it?
Around ~40 dB in typical rooms—audible but calm.
Can I solo‑mine with it?
You can, but solo is lottery—payout only if you find a block. Prefer a pool for steady sats.
Does it include a PSU?
Some kits do; others don’t. Confirm voltage/connector and buy a quality DC adapter if needed.
Is Wi‑Fi supported?
The unit focuses on Ethernet; use a small Wi‑Fi bridge if cable isn’t possible.
