Questions
What parts does the MAX VISOR PCB use?
52 parts, built around the 74HC245D. 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 MAX VISOR PCB KiCad files?
From the zgrate/ProtOs repository on GitHub, at the commit this page was made from: the board is schematics/simple_visor_board/MAX_VISOR_PCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MAX VISOR PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask zgrate before reusing the design.
