Questions
How big is the Soil moisture module PCB?
It measures 116.8 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Soil moisture module use?
27 parts. 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 Soil moisture module KiCad files?
From the tessel/smm repository on GitHub, at the commit this page was made from: the board is soil-moisture-module/soil-moisture-module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Soil moisture module design in my own project?
Its repository states no licence, so its author keeps all rights: ask tessel before reusing the design.
