Questions
How big is the Water Alarm PCB?
It measures 52 × 37.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Water Alarm use?
11 parts. 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 Water Alarm KiCad files?
From the kershen-bot/KiCad-Tutorial repository on GitHub, at the commit this page was made from: the board is Files/Water Alarm.kicad_pcb and its schematic Files/Water Alarm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Water Alarm design in my own project?
Its repository states no licence, so its author keeps all rights: ask kershen-bot before reusing the design.
