Questions
How big is the Front panel PCB?
It measures 35 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Front panel use?
16 parts. 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 Front panel KiCad files?
From the evilosa/lead-machine repository on GitHub, at the commit this page was made from: the board is electronic/front-panel/front-panel.kicad_pcb and its schematic electronic/front-panel/front-panel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Front panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask evilosa before reusing the design.
