Questions
How big is the Wiring PCB?
It measures 44.2 × 32.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wiring use?
49 parts, built around the LMV358, B5819W, 100UF/35V and BC817-40. 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 Wiring KiCad files?
From the esp-ebus/ebus-adapter-hardware repository on GitHub, at the commit this page was made from: the board is wiring.kicad_pcb and its schematic wiring.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wiring design in my own project?
Its repository states no licence, so its author keeps all rights: ask esp-ebus before reusing the design.
