Questions
How big is the Wifi fan PCB?
It measures 167.6 × 52.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wifi fan use?
34 parts, built around the LM386 and PN2222A. 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 Wifi fan KiCad files?
From the riverbots42/2023 repository on GitHub, at the commit this page was made from: the board is wifi-fan/pcb/wifi-fan/wifi-fan.kicad_pcb and its schematic wifi-fan/pcb/wifi-fan/wifi-fan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wifi fan design in my own project?
Its repository states no licence, so its author keeps all rights: ask riverbots42 before reusing the design.
