Questions
How big is the WaterLevelDetectorBatteryOp PCB?
It measures 72 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WaterLevelDetectorBatteryOp use?
16 parts, built around the ESP-07, AMS1117-3.3 and AMS1117-5.0. 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 WaterLevelDetectorBatteryOp KiCad files?
From the morynicz/WaterLevelDetector repository on GitHub, at the commit this page was made from: the board is WaterLevelDetectorBatteryOp.kicad_pcb and its schematic WaterLevelDetectorBatteryOp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WaterLevelDetectorBatteryOp design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
