Questions
How big is the Rcbus parallel PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rcbus parallel use?
17 parts, built around the 74HCT04D and 74HCT688D. 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 Rcbus parallel KiCad files?
From the electrified/rcbus-parallel-site repository on GitHub, at the commit this page was made from: the board is 0.0.0-pre-bdd0f15/Browse/rcbus-parallel.kicad_pcb and its schematic 0.0.0-pre-38663f3/Browse/rcbus-parallel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rcbus parallel design in my own project?
Its repository states no licence, so its author keeps all rights: ask electrified before reusing the design.
