Questions
How big is the WLS3 PCB?
It measures 28 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WLS3 use?
43 parts, built around the NE555P, BC547 and IRF9540NS. 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 WLS3 KiCad files?
From the bwillaert/WaterLevelSensor repository on GitHub, at the commit this page was made from: the board is PCB/WLS3/WLS3/WLS3.kicad_pcb and its schematic PCB/WLS/WLS/WLS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WLS3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bwillaert before reusing the design.
