Electrical connections
Important: Do not power the board by USB and an external power supply at the same time! The Din pin of the first LED is connected to pin D4 (GPIO2) of the Wemos D1 mini. Two of the mounting holes are connected to GND, two of the holes are connected to 5V. You can use this feature to stack multiple 38c3PCBLEDc100R Boards with brass spacers.

Questions
What parts does the 38c3PCBLEDC100R Rev.0 use?
28 parts, built around the WEMOS D1 MINI, WS2812D-F5 and ZVNL110A. 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 38c3PCBLEDC100R Rev.0 KiCad files?
From the c3re/38c3PCBLEDC100R repository on GitHub, at the commit this page was made from: the board is Rev.0/CAD/38c3PCBLEDC100R_Rev.0.kicad_pcb and its schematic Rev.0/CAD/38c3PCBLEDC100R_Rev.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 38c3PCBLEDC100R Rev.0 design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
