Questions
How big is the Probe2.1 PCB?
It measures 140.3 × 23.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Probe2.1 use?
22 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 Probe2.1 KiCad files?
From the Miceuz/SoilMoistureSensor repository on GitHub, at the commit this page was made from: the board is Probe2.1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Probe2.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Miceuz before reusing the design.
