Questions
How big is the WaterQualityControl PCB?
It measures 67.3 × 96.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WaterQualityControl use?
142 parts, built around the DRV8870DDA, ADS1115IDGS, PCA9685PW and K7805-2000R3L. 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 WaterQualityControl KiCad files?
From the Hasatio/WaterQualityControl repository on GitHub, at the commit this page was made from: the board is Rev0/Rev0.kicad_pcb and its schematic Rev0/Rev0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WaterQualityControl design in my own project?
Its repository states no licence, so its author keeps all rights: ask Hasatio before reusing the design.
