Questions
How big is the Lights PCB?
It measures 17.3 × 547.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lights use?
185 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 Lights KiCad files?
From the featherfly12/rainbow-pcb repository on GitHub, at the commit this page was made from: the board is lights/lights.kicad_pcb and its schematic external wearable.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lights design in my own project?
Its repository states no licence, so its author keeps all rights: ask featherfly12 before reusing the design.
