Questions
What parts does the 420nm use?
2 parts, built around the XEGAVT-H0-0000-000-000000K2001. 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 420nm KiCad files?
From the Open-Visual-Stimulator/LED_driver repository on GitHub, at the commit this page was made from: the board is single_led/420nm/PCB/PCB.kicad_pcb and its schematic board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 420nm 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).
