Questions
How big is the SL Christmas Tree A PCB?
It measures 85.7 × 133.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SL Christmas Tree A use?
70 parts, built around the SK6812MINI-E. 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 SL Christmas Tree A KiCad files?
From the Sternenlabor/Christmas_Tree_PCB repository on GitHub, at the commit this page was made from: the board is SL_Christmas_Tree_A/SL_Christmas_Tree_A.kicad_pcb and its schematic SL_Christmas_Tree_A/SL_Christmas_Tree_A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SL Christmas Tree A design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sternenlabor before reusing the design.
