Questions
How big is the PWM Fan Controller PCB?
It measures 80 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PWM Fan Controller use?
8 parts, built around the ARDUINO UNO R3 and IRLZ44N. 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 PWM Fan Controller KiCad files?
From the Sarkis-S/Embedded-Systems repository on GitHub, at the commit this page was made from: the board is PWM_Fan_Controller/source/PWM_Fan_Controller.kicad_pcb and its schematic Embedded_Security_Panel/archive/RevA/source/Security_Panel_revA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PWM Fan Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sarkis-S before reusing the design.
