Questions
How big is the Fan controller PCB?
It measures 32 × 19 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Fan controller use?
21 parts, built around the L78L05CZ, 1N5819WS and AO3400A. 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 controller KiCad files?
From the flaviut/fan-controller repository on GitHub, at the commit this page was made from: the board is fan-controller.kicad_pcb and its schematic fan-controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fan controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask flaviut before reusing the design.
