Questions
How big is the PicoIrrigation PCB?
It measures 108 × 88.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PicoIrrigation use?
156 parts, built around the MAX3232ID and MAX40200AUK. 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 PicoIrrigation KiCad files?
From the freudenthal/PicoIrrigation repository on GitHub, at the commit this page was made from: the board is PicoIrrigation.kicad_pcb and its schematic AnaloguePin.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoIrrigation design in my own project?
Its repository states no licence, so its author keeps all rights: ask freudenthal before reusing the design.
