Questions
How big is the Christmas tree PCB?
It measures 66 × 93.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Christmas tree use?
65 parts, built around the 19-C47/RSGHBHC-5V01/2T, 74LVC1T45W6 and NCP45525IMNTWG-H. 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 Christmas tree KiCad files?
From the azonenberg/misc-devboards repository on GitHub, at the commit this page was made from: the board is christmas-tree/christmas-tree.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Christmas tree design in my own project?
Its repository publishes it under the BSD-3-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).
