Questions
How big is the Fan Controller PCB?
It measures 35 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Fan Controller use?
48 parts, built around the LM51571RTE, ESP32-C6-MINI-1, RT9193-33GB and 1N4148WS. 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 acha666/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 acha666 before reusing the design.
