Questions
How big is the Cooling System PCB?
It measures 27 × 24 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Cooling System use?
13 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 Cooling System KiCad files?
From the itsmeibii/RCCooling_System repository on GitHub, at the commit this page was made from: the board is Cooling_System.kicad_pcb and its schematic Cooling_System.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cooling System design in my own project?
Its repository states no licence, so its author keeps all rights: ask itsmeibii before reusing the design.
