Questions
How big is the MuLight PCB?
It measures 49.2 × 47.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MuLight use?
18 parts, built around the SK12D07VG5 and BS-02-A1AJ010. 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 MuLight KiCad files?
From the MrMoDDoM/MuLight repository on GitHub, at the commit this page was made from: the board is MuLight.kicad_pcb and its schematic MuLight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MuLight design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
