Bitaxe Supra
Silent solo miner for your desk. Uses BM1368 chip from the S21 generation. Powered by 5V barrel jack, NOT USB-C.
Open Source Hardware
This miner is built on open-source hardware designs — transparent schematics published for anyone to audit, modify, and manufacture. No vendor lock-in, no proprietary firmware, and community-verified security.
Every Bitcoiner who cares about decentralization should own open-source mining hardware. It is the ultimate expression of hardware sovereignty — no single company controls the design, the firmware, or your ability to mine.
Explore the Bitaxe Hub →Open Source Miners United
Open Source Miners United (OSMU) is the community movement behind open-source Bitcoin mining hardware. The designs were published openly, enabling permissionless manufacturing worldwide — ensuring no single entity controls mining hardware production.
D-Central is a pioneer manufacturer in the OSMU ecosystem — involved since the very beginning. We created the original Bitaxe Mesh Stand, developed leading heatsinks and accessories, and stock every variant. When you buy from D-Central, you support a company that helped build this movement.

This device is assembled and quality-tested by D-Central Technologies in Canada. As a pioneer manufacturer in the open-source mining ecosystem, D-Central has been building these devices since the very beginning — creating the original Bitaxe Mesh Stand and developing leading accessories like custom heatsinks, cases, and power solutions.
When you buy from D-Central, you get a device built by engineers who understand Bitcoin mining hardware inside and out. Every unit undergoes thorough testing before shipping, and is backed by Canadian-based technical support and the ASIC repair expertise that comes from servicing thousands of miners.
Supporting manufacturers like D-Central is how open-source hardware achieves real decentralization — multiple independent producers worldwide, each building from the same open designs, ensuring no single entity controls the supply chain. Your purchase directly supports this mission.
Shop D-Central Miners →Built for Solo Mining
Solo mining means mining independently — no pool, no shared rewards. One lucky hash wins the entire block reward. Low-power miners like this one are perfect for solo mining: the electricity cost is negligible, so you can run 24/7 as a perpetual lottery ticket.
Every hash has an equal chance. Every hash counts.

Heating offset estimates the value of heat replacing an electric space heater during heating season (~6 months/year in Canada). Actual savings depend on your heating setup and climate.
Solo Mining Estimate
Solo mining is a lottery. There is no guarantee of finding a block. These estimates are based on current network difficulty and your hashrate. Every hash has an equal chance.

Frequently Asked Questions
Is the Bitaxe Supra profitable?
At $0.07/kWh, the Bitaxe Supra currently operates at a daily loss of $0.01. However, profitability can improve with lower electricity rates or rising BTC prices. If used as a space heater, the heating offset may make it economically viable.
Can I mine Bitcoin at home with the Bitaxe Supra?
Yes, the Bitaxe Supra scores 70/100 for home mining viability. It produces 35 dB of noise and draws 15W. It is suitable for home environments with appropriate placement considerations.
Can the Bitaxe Supra heat my home?
The Bitaxe Supra outputs approximately 51.2 BTU/hr of heat. For reference, a typical space heater produces 5,000-5,500 BTU/hr. All electrical energy consumed by the miner is converted to heat, making it 100% efficient as a heater. D-Central offers Bitcoin Space Heater builds designed specifically for home heating integration.
What power supply does the Bitaxe Supra need?
The Bitaxe Supra draws 15W of power. You need a power supply rated for at least 17W with appropriate voltage (5V DC (barrel jack 5.5x2.1mm)). D-Central stocks compatible power supplies in our shop. Always use a quality PSU from a reputable manufacturer to protect your investment.
