Questions
How big is the AllSerial eBus PCB?
It measures 67.4 × 44.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AllSerial eBus use?
40 parts, built around the SD103AWS, BC847, BC857 and BZT52C7V5S. 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 AllSerial eBus KiCad files?
From the Phunkafizer/AllSerial repository on GitHub, at the commit this page was made from: the board is Slaveboards/eBus/Board/AllSerial eBus.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the AllSerial eBus design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
