Bitaxe SupraHex 701 Solo Miner – Technical Overview
The Bitaxe SupraHex 701 Solo Miner is a compact, open-source Bitcoin mining device engineered for home and small-scale use.
As the latest model in the Bitaxe series, it integrates six BM1368 ASIC chips (the same chips used in Bitmain’s Antminer S21) to deliver a hashrate of approximately 3.5–4.2 TH/s while drawing only about 75 W of power at 12 V. This yields an energy efficiency of roughly 17.5 W/TH, on par with modern industrial mining rigs.
Yet the SupraHex 701 operates with just a single quiet 80×80 mm fan and minimal heat output, making it suitable for desktop or office environments. It is a standalone miner built around an on-board ESP32-S3 microcontroller with Wi-Fi connectivity, running the custom AxeOS firmware to support both solo and pool mining without requiring an external computer.
Notably, the Bitaxe SupraHex 701 features a fully open-source hardware and software design, providing transparency and allowing enthusiasts to inspect or modify its code and schematics.
