Questions
What parts does the Camp front use?
31 parts, built around the TLP293-4(E, BC847W, 1N4148WS and EE2-5NU. 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 Camp front KiCad files?
From the Nulifier/camp-ctrl repository on GitHub, at the commit this page was made from: the board is boards/camp-front/camp-front.kicad_pcb and its schematic boards/camp-front/camp-front.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Camp front design in my own project?
Its repository states no licence, so its author keeps all rights: ask Nulifier before reusing the design.
