Questions
How big is the WLS PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WLS use?
56 parts, built around the PIC16F1824-E/P, 78L05, NE555 and BS170. 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 WLS KiCad files?
From the bwillaert/WaterLevelSensor repository on GitHub, at the commit this page was made from: the board is PCB/WLS/WLS/WLS.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 WLS design in my own project?
Its repository states no licence, so its author keeps all rights: ask bwillaert before reusing the design.
