Questions
How big is the Fan Humidity PCB?
It measures 87.5 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fan Humidity use?
10 parts, built around the DHT11. 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 Fan Humidity KiCad files?
From the leebirdae/kicad repository on GitHub, at the commit this page was made from: the board is Fan_Humidity/kicad.kicad_pcb and its schematic Fan_Humidity/kicad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fan Humidity design in my own project?
Its repository states no licence, so its author keeps all rights: ask leebirdae before reusing the design.
