Questions
How big is the Dehumidifier PCB?
It measures 27.9 × 60.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dehumidifier use?
26 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 Dehumidifier KiCad files?
From the gehel/electronics repository on GitHub, at the commit this page was made from: the board is dehumidifier/dehumidifier.kicad_pcb and its schematic a320/overhead/lights/a320-overhead-lights/a320-overhead-lights.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dehumidifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask gehel before reusing the design.
