Questions
How big is the Motion sensor hardware PCB?
It measures 76.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motion sensor hardware use?
59 parts, built around the ESP32-C3-MINI-1-N4, SN74LV1T125DCK, USBLC6-2SC6 and FXL0630-6R8-M. 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 Motion sensor hardware KiCad files?
From the dbwalker0min/motion-sensor-hardware repository on GitHub, at the commit this page was made from: the board is hardware/motion-sensor-hardware.kicad_pcb and its schematic hardware/motion-sensor-hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motion sensor hardware design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
