What Is a Bitaxe? The Beginner's Guide to Open-Source Home Bitcoin Mining
If you've spent any time in Bitcoin mining circles lately, you've heard the word "Bitaxe" come up constantly. Forums, Reddit threads, Discord servers — everyone seems to be building one, buying one, or talking about one. So what exactly is it, and why does it matter?
Here's the plain-English version.
The Short Answer: A Tiny, Open-Source Bitcoin ASIC Miner
A Bitaxe is a small, open-source ASIC (Application-Specific Integrated Circuit) miner designed specifically for Bitcoin. It uses the same class of mining chips found in industrial-grade rigs — chips like the BM1368 and BM1370 — but packages them into a compact, affordable, community-built board that anyone can buy, assemble, or modify.
Unlike commercial mining equipment from large manufacturers, the Bitaxe is fully open source. The hardware schematics, firmware, and design files are freely available on GitHub. That means anyone in the community can inspect it, improve it, manufacture it, or build accessories for it. No black boxes. No locked firmware. No vendor lock-in.
It was created by Skot9000, a hardware engineer and Bitcoiner who wanted a small, accessible miner he could run at home — and decided to build one himself when nothing on the market fit the bill. Sound familiar? It's the same reason we started Ix Tech.
How Does a Bitaxe Actually Work?
At its core, a Bitaxe does exactly what any Bitcoin miner does: it runs SHA-256 hashing computations as fast as possible, competing to find the next valid Bitcoin block.
The difference is scale. Where an industrial mining farm runs thousands of ASICs producing petahashes of compute power, a Bitaxe produces somewhere in the range of 400 GH/s to 1.2 TH/s depending on the model — a fraction of the network total. That means your odds of solo mining a block are extremely low (think lottery odds), but that's kind of the point for most home miners. It's about participation, learning, and the genuine thrill of the attempt.
Many Bitaxe miners connect to a solo mining pool like CK Pool, where your hashrate is pointed directly at the Bitcoin network. If you find a block — and people do, occasionally — you keep the full reward.
Others run their Bitaxe pointed at a standard pool for small, consistent payouts or some choose a hybrid approach like Parasite pool.
The Bitaxe Family: Which Model Is Which?
The Bitaxe ecosystem has grown into several distinct models, each with different performance characteristics:
Bitaxe Gamma (601/602/603) — The current mainstream model. Uses the BM1370 chip. A solid all-around choice for most home miners. The 602 adds refinements to the board layout and other changes over the 601.
Bitaxe Supra — An older model, now discontinued, that many miners still run. Uses the BM1368 chip and was known for solid efficiency. If you find one used, it's still a capable machine.
Bitaxe GT — A newer one that utilizes two BM1370 chips capable of up to 4Th. Runs hotter and requires more attention to cooling, but pushes more hashrate.
What About the Nerdaxe?
The NerdAxe is a close cousin of the Bitaxe — also open source, also community-built, but with some key hardware differences. The Nerdaxe gamma has much of the same components except the noticeably larger and full color LillyGo display. The NerdQAxe++ runs four BM1370 chips, pushing significantly higher hashrate than a standard single-chip Bitaxe. It's a popular upgrade path for miners who've outgrown their first board and want more performance without building a full rack.
We carry Nerdaxe hardware and accessories including the new NerdQX — one of the highest-performance builds in the open-source mining ecosystem designed and built by us with the community.
Why Home Miners Choose the Bitaxe
The honest answer: it's not primarily about profit. A Bitaxe running at 600 GH/s on your desk is not going to outmine a 50-megawatt facility in Texas. Anyone telling you otherwise is selling something.
Home miners choose the Bitaxe for reasons that don't show up on a profit calculator:
It's genuinely educational. Setting up a Bitaxe teaches you how Bitcoin mining actually works — hashing, difficulty adjustments, pool mechanics, network participation. It's hands-on learning you can't get from a YouTube video.
It supports decentralization. Every independent home miner adds a small amount of geographic and jurisdictional diversity to the Bitcoin network. That matters.
It's fun. There's something deeply satisfying about running a machine that's participating in the Bitcoin network 24/7 — especially if you built or configured it yourself.
The community is exceptional. The open-source Bitcoin mining community is one of the most collaborative, generous, and technically sharp groups in the Bitcoin ecosystem. Once you're in it, you'll understand why people stay.
What Do You Need to Get Started?
Getting a Bitaxe up and running is more approachable than most people expect. Here's the basic hardware list:
- The Bitaxe/Nerdaxe board itself — available as a DIY kit or pre-assembled and ready out of box available in our shop.
- A cooling solution — the stock heatsink and fan work fine, but upgrades help; check our El Mirage heatsink for Bitaxe and Nerdaxe cooling
- A case or stand — optional but recommended; our Bitaxe Stand – Halving Edition is a community favorite
- Wi-Fi and a pool — You can choose to run your own node and pool, connect to a solo pool or pool like Parasite.
If you aren't that ambitious out of the gate, you can buy one ready to go from the shop. Setup time is typically under an hour even for first-timers and we have made some great videos on YouTube on How to Setup Your Bitaxe or Nerdaxe.
Why We Build for the Bitaxe Community
Ix Tech was born from the same frustration that created the Bitaxe itself: we couldn't find the parts and accessories we wanted for our own mining rigs, so we made them.
We're a Veteran and family-owned small business based in the USA. We design and manufacture 3D printed mining accessories, enclosures, and cooling solutions built specifically for open-source miners — and we laser-etch art for the desks and walls of people who love this technology as much as we do.
Everything we make is designed by people who actually use these machines. That's not a marketing line — it's why the products exist.
