Board thickness 1.6 mm Can use HASL or chem. Gold plating for silver or gold colored christmas ornaments
Populate boards accoring to silk screen prints Connectors belong to the side with the silk screen print Check LED function before assambling the tree Slide the two tree PCBs into each other and use symbols on PCBs to ensure correct orientation Afterwards use the same symbols as solder joints to give the tree more stability Lastely connect the brain PCB to the tree assembly
As of end 2024 the WLED software is marked experimental for ESP32-S3 chipset, therefore install WLED via https://wled-install.github.io/ and select an ESP32-S3 version (4 MB Flash).
After installation open WLED controls and load Presets and Configuration from Backup Files

Questions
How big is the ChristmasTree PCB?
It measures 129.5 × 184.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ChristmasTree use?
74 parts, built around the WS2812B. 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 ChristmasTree KiCad files?
From the RT-CUSTOMZ/3D-ChristmasTree repository on GitHub, at the commit this page was made from: the board is ChristmasTree_PCB1/ChristmasTree.kicad_pcb and its schematic ChristmasTreeBrain/ChristmasTreeBrain/ChristmasTreeBrain.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ChristmasTree design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
