What is a Bitaxe?

Quick answer

A Bitaxe is an open-source, single-chip Bitcoin ASIC miner: one Bitmain mining chip on a small board running open firmware (AxeOS). It is designed for learning, low-power solo mining and home use, not for hashrate-per-dollar against industrial machines. The hardware design and firmware are open and community-maintained.

This is a neutral community-reference page in the Bitaxe Answers Wiki. It has no product links — it exists to answer one question accurately. Credit for the Bitaxe goes to skot9000 and the Open Source Miners United (OSMU) community.

The Bitaxe is an open-source hardware project: the schematics, PCB layout and firmware are published so anyone can build, audit or modify the device. A typical Bitaxe is a single Bitmain mining ASIC (the same family of chip used in commercial Antminers) mounted on a compact board with its own controller, fan and web interface.

It exists for reasons that are not "compete with a data centre": education (you can see and change every part of a real miner), solo lottery mining (a small but non-zero chance of finding a whole block), and low-power home use (tens of watts, near-silent on the small models). A single-chip Bitaxe produces on the order of ~1 TH/s — millions of times below the total network — so it is best understood as a sovereign, hackable mining tool rather than a profit machine.

The project began with the original Bitaxe by skot9000 and is stewarded by the Open Source Miners United (OSMU) community, which maintains the firmware and coordinates the many hardware variants.
