Incase that wasn't obvious haha. Here is a repository of a bunch of PCB's I've made, from a heart lightboard for your lover (It works) to lampnodes that connect to a central server!

Questions
How big is the LampNode PCB?
It measures 126 × 74 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LampNode use?
22 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 LampNode KiCad files?
From the SaltyMelonYT/PCB-Projects repository on GitHub, at the commit this page was made from: the board is LampNode/Hardware/LampNode.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LampNode design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
