Questions
What parts does the Touchled use?
19 parts, built around the BSS138L and CR2032. 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 Touchled KiCad files?
From the jonnor/projects repository on GitHub, at the commit this page was made from: the board is jewelry/projectedtradition/touchled/touchled.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Touchled design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonnor before reusing the design.
