Questions
How big is the Train set building light PCB?
It measures 127 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Train set building light use?
54 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 Train set building light KiCad files?
From the dwilliams/pcb-things repository on GitHub, at the commit this page was made from: the board is train-set-building-light/train-set-building-light.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Train set building light design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
