Questions
How big is the Window sensor PCB?
It measures 92.5 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Window sensor use?
22 parts, built around the ATMEGA328P-AU and BAT54CW. 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 Window sensor KiCad files?
From the judos/pcb_window_sensor repository on GitHub, at the commit this page was made from: the board is window_sensor/window_sensor.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Window sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask judos before reusing the design.
