Questions
How big is the XmasTree PCB?
It measures 168 × 133 mm and has 2 copper layers, 1.6 mm thick.
What parts does the XmasTree use?
37 parts, built around the ESP32-WROOM-32, WS2812B and BSS138. 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 theloukou/xmasSmartTree repository on GitHub, at the commit this page was made from: the board is PCB/xmasTree.kicad_pcb and its schematic PCB/base/base.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 theloukou before reusing the design.
