Questions
What parts does the Lamp use?
47 parts, built around the STM32F030F4P6, LMV321, MIC5205-3.3YM5 and TPS54620RGY. 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 Lamp KiCad files?
From the bgamari/lamp repository on GitHub, at the commit this page was made from: the board is board/v1/lamp.kicad_pcb and its schematic board/v2/lamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lamp design in my own project?
Its repository states no licence, so its author keeps all rights: ask bgamari before reusing the design.
