Questions
How big is the LED Chain PCB?
It measures 63.6 × 31.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LED Chain use?
33 parts, built around the 74LS04PC and IRLML2502. 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 LED Chain KiCad files?
From the SteveMayze/LED_Chain repository on GitHub, at the commit this page was made from: the board is kicad/LED_Chain.kicad_pcb and its schematic kicad-12v/LED_Chain_12V.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LED Chain design in my own project?
Its repository states no licence, so its author keeps all rights: ask SteveMayze before reusing the design.
