Questions
How big is the OpenPLC PCB?
It measures 129.5 × 72.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenPLC use?
165 parts, built around the LM2596S-5.0, TLP281-4, MAX3370EXK and 24LC32A/P. 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 OpenPLC KiCad files?
From the radioelf/OpenPlc repository on GitHub, at the commit this page was made from: the board is hard/cad/OpenPLC/OpenPLC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenPLC design in my own project?
Its repository states no licence, so its author keeps all rights: ask radioelf before reusing the design.
