Questions
How big is the Prox sensor PCB?
It measures 35.9 × 43.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Prox sensor use?
41 parts, built around the STM32L031G6U6, TPS61165DBV, BD4840G-TR and STHS34PF80. 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 Prox sensor KiCad files?
From the cornway/vanity_mirror_pcb repository on GitHub, at the commit this page was made from: the board is prox_sensor.kicad_pcb and its schematic LED-Driver-CC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prox sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask cornway before reusing the design.
