Questions
How big is the Bkm-129x ultimate PCB?
It measures 105 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bkm-129x ultimate use?
124 parts, built around the ATMEGA328PB-AU, 74LVC125AD, ISL4089IBZ and ISL59885ISZ. 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 Bkm-129x ultimate KiCad files?
From the bodgit/bkm-129x-ultimate repository on GitHub, at the commit this page was made from: the board is main/main.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bkm-129x ultimate design in my own project?
Its repository states no licence, so its author keeps all rights: ask bodgit before reusing the design.
