From the project
PC-AXE is a compact, PCIe x4-based, open-hardware Bitcoin miner designed to plug directly into desktop computers. Inspired by Bitaxe, Bitcrane, and professional mining cards, PC-AXE uses twelve BM1370 ASIC chips and a 6-phase high-efficiency buck converter to deliver up to 14.4TH
PC-AXE is a compact, PCIe x4-based, open-hardware Bitcoin miner designed to plug directly into desktop computers. Inspired by Bitaxe, Bitcrane, and professional mining cards, PC-AXE uses twelve BM1370 ASIC chips and a 6-phase high-efficiency buck converter to deliver up to 14.4TH/s of hashrate at just 200W power draw.
Note: PC-AXE is a work in progress. Hardware files are being finalized, and firmware development is ongoing. Community contributions and testing feedback are welcome.
