Questions
How big is the LimeLED PCB?
It measures 88.3 × 106.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LimeLED use?
48 parts, built around the SN74AHCT125N, TPSM863257RDXR, MBR20100DT and SD103AW. 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 LimeLED KiCad files?
From the LimesKey/LED-Christmas repository on GitHub, at the commit this page was made from: the board is LimeLED.kicad_pcb and its schematic LimeLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LimeLED 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).
