Questions
How big is the Smart lamp PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart lamp use?
93 parts, built around the LMR33620CDDA and WS2813C. 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 Smart lamp KiCad files?
From the jumper385/smart-lamp repository on GitHub, at the commit this page was made from: the board is smart_lamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart lamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask jumper385 before reusing the design.
