Questions
How big is the UMSwitch PCB?
It measures 60 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UMSwitch use?
44 parts, built around the LPC5526JBD64 and SC32S-7PF20PPM. 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 UMSwitch KiCad files?
From the vgskye/UMSwitch repository on GitHub, at the commit this page was made from: the board is umswitch.kicad_pcb and its schematic umswitch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UMSwitch design in my own project?
Its repository states no licence, so its author keeps all rights: ask vgskye before reusing the design.
