Nerdaxe Gamma Bitcoin Solo Miner - Made in Germany

The Nerdaxe Gamma is an open-source Bitcoin miner with a single BM1370 ASIC chip for solo mining at home. It is the big brother of the Bitaxe Gamma: the same chip and similar performance, plus a large colour display and stronger cooling out of the box. It is built in Germany and is CE compliant.

The Nerdaxe was developed by BitMaker, who released the device as open source.

• Large colour display. Hashrate, temperature and mining status are always visible on the device, even without a browser.
• ICE-Tower with Noctua fan as standard. The heatsink with copper heat pipe and the Noctua fan keep the Nerdaxe quiet even in continuous operation. Our ICE-Tower is engraved with the Bitcoin halving formula.
• Same chip as the Bitaxe. Hashrate and efficiency are on the level of the Bitaxe Gamma.

• BM1370 ASIC chip. The same chip as in the current Bitmain Antminer S21 Pro, assembled in Germany.
• 1.3 TH/s out of the box. The Nerdaxe Gamma delivers this hashrate without any additional upgrade.
• Efficiency. Fitted with high-quality components from the factory. Bitmain specifies an efficiency of 15 J/TH for this chip.
• Engraved power supply. A 31.2 W power supply (5.2 V / 6 A) with a laser-engraved ∞/21M logo is included.
• Made in Germany. From component selection to final assembly in Germany, with strict quality checks, CE compliant. More on our Bitaxe Made in Germany page.

Mining pool in Germany. Our pool runs in Germany, which means shorter latency for European miners. The only thing better is mining on your own Bitcoin node.

Open-source firmware. The firmware is developed by the community and can be customised. More in the firmware's GitHub repository.

• Compact design & Wi-Fi: The miner connects to your network via the built-in Wi-Fi, no network cable needed. It takes up little space and fits well at home or in the office.
• Colour display & web interface: The LILYGO T-Display shows the key figures right on the device. Setup via the web interface in your browser takes just a few minutes.

3. 3D-printed Nerdaxe stand

• Overclocking: At your own risk. Damage caused by operation outside the frequency and voltage range provided in the firmware (e.g. with custom or modified firmware) is not a defect of the device and is not covered by the legal guarantee.
• Care and maintenance: The Nerdaxe is a high-performance miner and needs regular dusting and care. You should renew the thermal paste at regular intervals; we recommend a change after about 6 months. It is necessary after 12 to 18 months at the latest.

The Nerdaxe Gamma is a CE-compliant Bitcoin miner built in Germany, with a large colour display and quiet cooling out of the box. It suits beginners, solo miners and experienced tinkerers who want to mine Bitcoin efficiently and in a decentralised way. Our mining pool in Germany keeps latency short.

What hashrate does the Nerdaxe Gamma deliver?
At least 1.3 TH/s out of the box, without any additional upgrade.

How does the Nerdaxe Gamma differ from the Bitaxe Gamma?
Both use the BM1370 chip and are on par in hashrate and efficiency. The Nerdaxe Gamma adds a large colour display and comes with an ICE-Tower with copper heat pipe and Noctua fan as standard.

How likely is it to find a block when solo mining?
Solo mining works like a lottery. With a network hashrate of around 990 EH/s (October 2026), a single Nerdaxe Gamma statistically finds a block about once every 14,500 years. The odds are the same every second, which is why small miners keep succeeding: in March 2025 a Bitaxe Ultra with around 480 GH/s found a full block.

Do I need my own Bitcoin node?
No. Enter the address of a solo pool and your Bitcoin address in the web interface, and you are done. With your own node you mine without any third party.

Does the power supply fit any socket?
In the EU, yes: it has an EU plug. For other countries, choose the variant "International Plug (Adapter Set)".

• Only operate with the supplied power supply.
• Use indoors in dry rooms only, not outdoors, in bathrooms or in damp rooms.
• The heatsink and circuit board get hot during operation. Do not touch while running.
• Keep the fan and ventilation openings clear. Do not cover the device or run it inside a closed cabinet.
• Place on a solid, non-flammable surface, not on paper, fabric or carpet.
• Unplug the power supply before dusting or replacing the thermal paste.
• Operate and store out of the reach of children.
• Do not dispose of with household waste. Take waste electrical equipment to a collection point.
