Questions
How big is the Sensor PCB?
It measures 68 × 38 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Sensor use?
38 parts, built around the DMP2045U. 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 leak-guard/hardware repository on GitHub, at the commit this page was made from: the board is manufacturing/sensor/sensor.kicad_pcb and its schematic leakguard.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 leak-guard before reusing the design.
