Questions
How big is the Christmas tree PCB?
It measures 113.9 × 145.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Christmas tree use?
40 parts, built around the ATMEGA48-20PU, TLC5940PWP, SEN-08880 and BC2AAPC. 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 healyf3/christmas_tree_pcb repository on GitHub, at the commit this page was made from: the board is 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 states no licence, so its author keeps all rights: ask healyf3 before reusing the design.
