Questions
How big is the PC Fan Controller PCB?
It measures 92 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PC Fan Controller use?
17 parts, built around the FZT651TA. 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 PC Fan Controller KiCad files?
From the jgoeszoom/PC-Fan-Controller repository on GitHub, at the commit this page was made from: the board is PC Fan Controller.kicad_pcb and its schematic PC Fan Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PC Fan Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask jgoeszoom before reusing the design.
