Questions
How big is the Lume PCB?
It measures 54 × 63 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lume use?
39 parts, built around the NCP583SQ28 and PMEG2020EH. 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 Lume KiCad files?
From the Kreyl/Lume repository on GitHub, at the commit this page was made from: the board is lume_hw/lume.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lume design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
