Questions
What parts does the PLC use?
41 parts, built around the LM2594M-3.3, LM2594M-5.0, SN74HC14PWR-TP and SS210. 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 PLC KiCad files?
From the EsqueletoArg/PLC-Semac-Rolo repository on GitHub, at the commit this page was made from: the board is PLC.kicad_pcb and its schematic PLC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PLC design in my own project?
Its repository states no licence, so its author keeps all rights: ask EsqueletoArg before reusing the design.
