Questions
How big is the RS422-WS2815 PCB?
It measures 94 × 18.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RS422-WS2815 use?
34 parts, built around the MAX485ED and EMK325ABJ107MM-T. 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 RS422-WS2815 KiCad files?
From the nm4c/RS422-WS2815 repository on GitHub, at the commit this page was made from: the board is rs422-ws2815.kicad_pcb and its schematic rs422-ws2815.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RS422-WS2815 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nm4c before reusing the design.
