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?
135 parts, built around the DRV8870DDA, ADS1115IDGS, PCA9685PW and TCA9534PW. 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 Rev1/Rev1.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.
