Questions
How big is the Probe1 PCB?
It measures 185.7 × 25.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Probe1 use?
19 parts, built around the 74LVC1G125 and 74LVC1G86W5. 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 Probe1 KiCad files?
From the Miceuz/SoilMoistureSensor repository on GitHub, at the commit this page was made from: the board is Probe1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Probe1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Miceuz before reusing the design.
