Questions
How big is the BitaxeBonanza PCB?
It measures 130 × 112 mm and has 6 copper layers, 1.6 mm thick.
What parts does the BitaxeBonanza use?
245 parts, built around the ESP32-S3-WROOM-1-N8, TPSM861253RDXR, TPS546D24ARVFR and SN74AVC4T774PW. 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 BitaxeBonanza KiCad files?
From the bitaxeorg/bitaxeBonanza repository on GitHub, at the commit this page was made from: the board is BitaxeBonanza.kicad_pcb and its schematic BitaxeBonanza.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BitaxeBonanza 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).
