Questions
How big is the Lightcoon PCB?
It measures 99.5 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightcoon use?
15 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 Lightcoon KiCad files?
From the rrrenai/lightcoon repository on GitHub, at the commit this page was made from: the board is src/lightcoon.kicad_pcb and its schematic src/lightcoon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightcoon design in my own project?
Its repository states no licence, so its author keeps all rights: ask rrrenai before reusing the design.
