Questions
How big is the XmasTree PCB?
It measures 80.7 × 95.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XmasTree use?
36 parts, built around the FT231XS-R, WS2813B-B and BSN20. 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 XmasTree KiCad files?
From the YorkEngSoc/XmasTree repository on GitHub, at the commit this page was made from: the board is XmasTree.kicad_pcb and its schematic XmasTree.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XmasTree design in my own project?
Its repository states no licence, so its author keeps all rights: ask YorkEngSoc before reusing the design.
