Questions
How big is the Under bed lighting PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Under bed lighting use?
58 parts, built around the SN74LVC08ADRG3, 1812L110/33V, AO3400A and SMBJ26CA. 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 Under bed lighting KiCad files?
From the dbwalker0min/under-bed-lighting repository on GitHub, at the commit this page was made from: the board is electrical/under-bed-lighting.kicad_pcb and its schematic electrical/led-driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Under bed lighting 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).
