Questions
How big is the Light ctl PCB?
It measures 106 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Light ctl use?
19 parts, built around the ATMEGA328PB-AU. 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 Light ctl KiCad files?
From the kiu/lightdesk repository on GitHub, at the commit this page was made from: the board is kicad/light-ctl/light-ctl.kicad_pcb and its schematic kicad/light-box/light-box.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light ctl design in my own project?
Its repository states no licence, so its author keeps all rights: ask kiu before reusing the design.
