The Bitaxe Gamma is the the world’s first open source bitcoin miner, allowing you to mine to a pool, lottery mine or solo mine without the huge costs, power consumption or noise of traditional Bitcoin mining rigs. It's an easy way to get started with serious, open-source Bitcoin mining with modern ASIC silicon.
This is our Bitaxe Gamma 602 Kit - including a Bitaxe Gamma 602 board, a 5V 6A multi-head power supply (includes heads for UK, EU and USA), 3D-printed case, metal stand, heatsink and 40mm cooling fan. It's everything you need to get started - perfect for anyone who wants to plug in, point at a pool and start mining - or tinker, overclock and experiment with different settings.
The Gamma uses a BM1370 Bitmain chipfrom the Bitmain S21 miner, mining up to 1.2 TH/s of hashrate and designed to be incredibly power efficient whilst also quiet enough to run in the home. There is also an ESP32 controller alongside this, hosting a local web page for configuration and information as well as in built wireless networking - removing the need for an external computer.
Open-source design & firmware
The Bitaxe Gamma 602 is part of the wider Bitaxe ecosystem – an open-source Bitcoin ASIC miner project using modern chips like the BM1370. Hardware design files live on GitHub, and firmware is provided by the Bitaxe Gamma repository and ESP-Miner firmware.
That means you’re free to audit, modify and extend the device – whether that’s tweaking cooling, integrating it into a swarm, writing your own monitoring scripts or experimenting with different voltage/frequency curves.
Features
Modern ASIC: BM1370 SHA-256 chip taken from the Antminer S21 family, capable of around 1.2 TH/s on a single chip
Open-source hardware & firmware: based on the Bitaxe Gamma design and AxeOS firmware, with design files and code available on GitHub
Standalone miner: no external computer required – mines directly over Wi-Fi
Low power: powered from a 5V 6A PSU (included), suitable for desks, shelves and home labs
Beginner friendly: easy web dashboard for configuration and monitoring
Advanced ready: full access to frequency, voltage and pool settings for tuning and experimentation
Ready to run: kit includes everything you need, including multi-head PSU, heatsink/fan, stand and case
