Questions
How big is the Switch machine PCB?
It measures 42.2 × 36.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switch machine use?
27 parts, built around the UVR1V102MHD, 0686F2500-01, B550C and DDZ5V6BSF. 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 Switch machine KiCad files?
From the Lambosaurus/Train-Controller-HW repository on GitHub, at the commit this page was made from: the board is switch_machine/switch_machine.kicad_pcb and its schematic Controller/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch machine design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lambosaurus before reusing the design.
