Braiins Mini Miner BMM 101
The Braiins Mini Miner BMM 101 is a small, finished desk miner from Braiins, the company behind Braiins OS. It does about 1 TH/s at 40 W by default, up to 80 W overclocked, at around 40 dB. It has both Ethernet and 2.4 GHz WiFi, a screen, an included power supply and a browser dashboard.

Good and less good
Good
- Ethernet port, unlike Bitaxe-style miners.
- Finished case, screen and power supply; feels like a consumer product.
- Quiet at default settings and backed by an established mining company.
Less good
- About 40 J/TH: less efficient than a Bitaxe Gamma (about 15 J/TH) at a similar hashrate.
- Costs two to three times as much as a Bitaxe Gamma for about the same hashrate.
- At about 1 TH/s, solo blocks are a long shot and pool payouts are small.
Set it up on DirectPool
The BMM 101 runs Braiins OS with a web dashboard. Plug in Ethernet (simplest), read the IP address on the screen or in your router, and open it in a browser.
- Pool URL
- stratum+tcp://stratum.directpool.io:3333
- Username
- your_bc1_address.worker_name
- Password
- x
Replace your_bc1_address with a Bitcoin address you control (bc1 or 3). The part after the dot is a name for this machine, so you can tell your miners apart. Addresses starting with 1 are not accepted.
- 1.Plug in the power supply and, ideally, a network cable. For WiFi, follow the on-screen instructions to join a 2.4 GHz network.
- 2.Find the miner's IP address on its screen or in your router's device list, and open it in a browser on the same network.
- 3.Log in to Braiins OS and open the pool settings.
- 4.Replace the default pool with the values above, keeping stratum+tcp:// and :3333 in the URL.
- 5.Save. Braiins OS applies the change and the dashboard shows hashrate within a few minutes.
Common mistakes
- Leaving the default pool as the first entry. Put DirectPool first, or remove the default.
- Dropping the stratum+tcp:// prefix or the :3333 port from the Pool URL.
- Typing the Bitcoin address by hand. Copy and paste it into Username.
- Overclocking to 80 W without good airflow. Double the power means double the heat and more fan noise.
After a few minutes, paste your address on the pool page to see the machine. Small miners can take a while to send their first share.

Questions
- Braiins Mini Miner or Bitaxe Gamma?
- Similar hashrate. The Bitaxe Gamma is cheaper and uses about half the power. The BMM 101 adds Ethernet, a finished case and Braiins support.
- Can the BMM 101 mine on any pool?
- Yes. Enter stratum+tcp://stratum.directpool.io:3333 as the pool URL, your bc1 address plus .worker as the username, and x as the password.
- Does it support Ethernet?
- Yes, a 100 Mbit/s port, plus 2.4 GHz WiFi. Ethernet is the more reliable choice.
- How loud is it?
- Around 40 dB at default settings, like a quiet fridge. It gets louder when overclocked.
- How much electricity does it use?
- About 350 kWh a year at 40 W, so about 70 a year at 0.20 per kWh.
