Questions
What parts does the Sensor use?
53 parts, built around the SIT1042AQT/3, LMR16030SDDAR, HX711 and B560C. 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 Sensor KiCad files?
From the 86kkd/millionBoard repository on GitHub, at the commit this page was made from: the board is pcb/sensor/sensor.kicad_pcb and its schematic pcb/GPS_Audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask 86kkd before reusing the design.
