Questions
How big is the FanControl PCB?
It measures 72.8 × 38 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FanControl use?
104 parts, built around the CH340B, ESP-12E, DS18B20+ and LM2575T-ADJ. 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 FanControl KiCad files?
From the bakadave/fanControl repository on GitHub, at the commit this page was made from: the board is PCB/fanControl/fanControl.kicad_pcb and its schematic PCB/fanControl/fanControl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FanControl design in my own project?
Its repository states no licence, so its author keeps all rights: ask bakadave before reusing the design.
