Questions
How big is the Window Comparator PCB?
It measures 64 × 50.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Window Comparator use?
28 parts, built around the LM393. 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 Comparator KiCad files?
From the Avyukth-ma/Electronics-Projects repository on GitHub, at the commit this page was made from: the board is Window Comparator/Window Comparator.kicad_pcb and its schematic Dual Rail Power Supply/Dual Rail Power Supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Window Comparator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Avyukth-ma before reusing the design.
