Description
The QAxe is a quad-BM1366 open-source Bitcoin miner that packs serious solo mining power into a compact, desktop-friendly form factor. With four of Bitmain’s efficient BM1366 ASIC chips delivering an average of 1.7 TH/s, the QAxe gives lottery miners a meaningful chance at finding a full Bitcoin block while running quietly at home. This is open-source mining hardware for Bitcoiners who believe decentralization starts with a hash.

Quad-Chip Solo Mining Power
Where single-chip miners like the Bitaxe deliver 500-800 GH/s, the QAxe quadruples the silicon with four BM1366 chips pushing ~1.7 TH/s. That is roughly 2-3x the hashrate of a standard Bitaxe, giving you proportionally better odds in the solo mining lottery. Every additional hash per second increases your probability of finding a block and claiming the full block reward.
12V XT30 Power — Simple and Universal
The QAxe runs on 12V DC via a standard XT30 connector — the same type used in the Bitaxe Hex and many other open-source miners. This means you can power it from a 12V PSU, a bench power supply, or even a 12V battery system for off-grid mining. No proprietary power bricks, no hard-to-find connectors.
Fully Open Source
The QAxe is built on open-source principles from the ground up. Hardware designs, firmware, and documentation are publicly available under the GPL-3.0 license. You can inspect every line of code, verify what your miner is doing, modify it to suit your needs, or contribute improvements back to the community. This is Bitcoin mining without black boxes.
Community-Driven Development
The QAxe was born from the open-source mining community, with rev3 introducing improvements like corrected capacitor placement and a Boot-Switch for easier firmware updates. By purchasing a QAxe, you are supporting the ecosystem of developers who believe mining hardware should be transparent, modifiable, and accessible to individuals — not just corporations.
Supporting Open-Source Mining Innovation
For every QAxe sold, $10 is remitted to Open Source Miners United in support of their innovative open-source efforts that contribute to the development of these miners and the broader decentralized mining ecosystem.

Frequently Asked Questions
What PSU do I need for the QAxe?
The QAxe requires a 12V DC power supply with an XT30 connector. A standard 12V/10A PSU with XT30 output will work. Do not power it via USB — the USB port is for firmware flashing and serial communication only, not power delivery.
Can I mine in a pool instead of solo?
Yes. While the QAxe is optimized for solo (lottery) mining, it supports pool mining as well. You configure the mining target through the web interface over WiFi.
How does the QAxe compare to a Bitaxe?
The QAxe runs four BM1366 chips versus the Bitaxe’s single chip, delivering roughly 2-3x the hashrate. It draws more power accordingly. Choose the QAxe if you want higher solo mining odds; choose a Bitaxe for the most compact and lowest-power entry point.
Is the QAxe noisy?
The QAxe is designed for desktop use and runs quietly compared to full-size ASIC miners. Noise levels are comparable to a small electronics project — not silent, but perfectly acceptable in a home office environment.
How do I update the firmware?
Rev3 of the QAxe supports firmware updates via USB Bootloader, making the process straightforward. Earlier revisions use a CMSIS-DAP Programmer. Full instructions are available in the open-source documentation.
Why Buy from D-Central?
D-Central Technologies has been a pioneer in the open-source mining hardware ecosystem. We stock the QAxe because we believe in the mission: decentralizing Bitcoin mining one miner at a time. Our team can help you set up, configure, and troubleshoot your QAxe — because we are miners ourselves. Every hash counts.
