Description
Why the NerdQAxe — The Original Quad-Chip Open Source Bitcoin Solo Miner
The NerdQAxe is the miner that started the quad-chip revolution. Before the NerdQAxe, open-source solo mining topped out at single-chip hashrates. Designed by shufps and built on the QAxe architecture, the NerdQAxe packed four BM1366 chips onto one board and proved that multi-chip open-source mining was not only possible — it was practical.
- The original quad-chip open-source Bitcoin miner — four BM1366 ASIC chips (the same silicon that powered the Antminer S19 XP) working in parallel, delivering 1.7–2.4 TH/s of SHA-256 hashrate.
- Serious solo mining power on a budget — at clearance pricing, the NerdQAxe offers one of the most affordable ways to run a quad-chip solo miner. Your block-finding odds scale directly with hashrate.
- Plug-and-play operation — connect to Wi-Fi, enter your wallet address, and start mining through the browser-based AxeOS dashboard. The 1.9″ color LCD shows hashrate, temperature, and network stats in real time.
- The stepping stone that built an ecosystem — every quad-chip OSMU miner that followed owes its architecture to the original QAxe design. The NerdQAxe+ and NerdQAxe++ are direct descendants of this hardware.
- Open-source through and through — full hardware schematics, firmware source code, and design files are publicly available on GitHub. You own the hardware and the knowledge behind it.
The NerdQAxe is end-of-life — once current stock is gone, it is gone. For miners who want to own a piece of OSMU history while running meaningful hashrate at a fraction of the cost of its successors, this is the window.
D-Central Technologies is a pioneer in the open-source mining ecosystem. We have been building, testing, and shipping OSMU hardware since the early days — including creating the original Bitaxe Mesh Stand and developing custom heatsinks used across the lineup. Every NerdQAxe ships from our facility in Laval, Quebec, hand-inspected by our ASIC repair technicians. $5–$10 from every sale goes directly to OSMU development.

Frequently Asked Questions
What is the NerdQAxe?
The NerdQAxe is the first-ever quad-chip open-source Bitcoin solo miner. It uses four Bitmain BM1366 ASIC chips — the same silicon found in the Antminer S19 XP — to deliver 1.7–2.4 TH/s of SHA-256 hashrate. It runs the open-source ESP-Miner firmware and connects via Wi-Fi for browser-based management through the AxeOS dashboard.
Why is the NerdQAxe end-of-life?
The NerdQAxe has been superseded by two newer models: the NerdQAxe+ (4x BM1368 chips, better efficiency) and the NerdQAxe++ (4x BM1370 chips, double the hashrate). The BM1366 chip generation has been succeeded by more efficient chips from newer Antminer series. The NerdQAxe still works perfectly and mines real Bitcoin — it is simply no longer in active production.
What are my chances of finding a Bitcoin block with the NerdQAxe?
At 2 TH/s against the current network hashrate (~800+ EH/s), your daily probability of finding a block is approximately 1 in 1.7 million. That works out to roughly 0.02% over a full year. The odds are long — but every hash has an independent, equal chance. Multiple OSMU miners have found solo blocks worth 3.125 BTC ($300,000+ CAD). The NerdQAxe is a lottery ticket that costs about $6–8/month in electricity.
What power supply do I need?
The NerdQAxe requires a 12V DC power supply rated for at least 10A (120W). A quality Mean Well or similar power supply with the correct barrel connector works well. Never use a 5V Bitaxe power supply — the NerdQAxe runs on 12V. We carry compatible power supplies in our accessories shop.
How loud is the NerdQAxe?
The NerdQAxe operates at approximately 40 dB — comparable to a quiet desktop computer fan. It is designed for 24/7 home or office operation. You can comfortably keep it on your desk or bookshelf without noise issues.
Which mining pool should I use?
For solo mining, the two most popular pools are Solo CKPool (solo.ckpool.org) — 2% fee, mature infrastructure, multiple confirmed block finds — and Public Pool (web.public-pool.io) — no fees, self-hostable, community-driven. For pool mining with predictable small payouts, Ocean and Braiins are solid options. Solo mining is the recommended use case for quad-chip miners.
Should I buy the NerdQAxe or upgrade to the NerdQAxe+?
If you are looking for the best value per dollar and do not mind slightly lower efficiency, the NerdQAxe at clearance pricing is hard to beat. The NerdQAxe+ offers better efficiency (~20 J/TH vs ~23–32 J/TH), quieter operation (<25 dBA), and uses newer BM1368 chips — but at a higher price. If budget is the priority, the NerdQAxe delivers. If efficiency and noise matter most, step up to the NerdQAxe+.
Can the NerdQAxe mine cryptocurrencies other than Bitcoin?
The NerdQAxe mines any SHA-256 cryptocurrency, including Bitcoin, Bitcoin Cash, and other SHA-256 coins. However, Bitcoin solo mining is the primary and recommended use case.
How do I update the firmware?
Open the AxeOS web dashboard in your browser (enter the device’s IP address), navigate to Settings, and use the firmware upload function to install the latest release. Updates take about 60 seconds. Always download firmware from the official GitHub repository. OTA (over-the-air) updates are supported — no USB cable required.
Does D-Central offer support and warranty?
Yes. Every NerdQAxe sold by D-Central is inspected by our ASIC repair technicians before shipping. If you need help with setup, troubleshooting, or hardware issues, our support team in Laval, Quebec is here. D-Central is also one of the leading ASIC repair shops in North America — if anything goes wrong, we fix miners for a living.
Can I buy the NerdQAxe in Canada?
Yes — and you should act fast. D-Central Technologies is based in Laval, Quebec, and the NerdQAxe is available at clearance pricing while supplies last. CAD pricing, fast Canadian shipping, bilingual support. Once current stock is gone, the NerdQAxe is retired permanently. Visit our shop before they are gone.
What if my NerdQAxe needs repair?
D-Central’s ASIC repair team has serviced 2,500+ mining machines since 2016, including the BM1366 chips inside the NerdQAxe. If your device develops any hardware issue, our technicians in Laval, Quebec can diagnose and repair it. We support everything we sell — even end-of-life products.
Supporting Open-Source Mining
The NerdQAxe is built on open-source hardware and software under the OSMU (Open Source Miners United) initiative. All design files, schematics, and firmware are publicly available on GitHub. Anyone can review, modify, and build on this technology — that is the point.
$5–$10 from every NerdQAxe sold by D-Central goes directly to the OSMU development fund, supporting the engineers and developers who design the next generation of open-source mining hardware. When you buy from D-Central, you are funding the decentralization of Bitcoin mining at the hardware level.
The NerdQAxe is licensed under open-source terms. Full source code and hardware designs: github.com/shufps/qaxe
