Questions
How big is the Light automation module PCB?
It measures 36 × 32.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Light automation module use?
20 parts, built around the VEML7700-TT, SI0301-TP and SS24FL. 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 automation module KiCad files?
From the antonyare93/light_automation_module repository on GitHub, at the commit this page was made from: the board is kicad/light_automation_module.kicad_pcb and its schematic kicad/light_automation_module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light automation module design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
