Questions
How big is the PhotoDiode PCB?
It measures 26 × 18 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PhotoDiode use?
10 parts, built around the SFH 206 K. 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 PhotoDiode KiCad files?
From the Sireis/Drawer-Opening-Tracker repository on GitHub, at the commit this page was made from: the board is support/PhotoDiode/PhotoDiode.kicad_pcb and its schematic support/PhotoDiode/PhotoDiode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PhotoDiode 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).
