Questions

How big is the BitaxeGT PCB?

It measures 65 × 112 mm and has 6 copper layers, 1.6 mm thick.

What parts does the BitaxeGT use?

187 parts, built around the ESP32-S3-WROOM-1-N8, TPSM861253RDXR, SN74AVC4T774PW and TC2030-IDC-NL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the BitaxeGT KiCad files?

From the bitaxeorg/BitaxeGT repository on GitHub, at the commit this page was made from: the board is BitaxeGT.kicad_pcb and its schematic ASIC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BitaxeGT design in my own project?

Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
