Questions
How big is the Luefter Controller PCB?
It measures 57 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Luefter Controller use?
17 parts, built around the DS18B20 and C100. 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 Luefter Controller KiCad files?
From the PeterKirschPiano/Fan-Controller repository on GitHub, at the commit this page was made from: the board is KiCad PCB/Luefter Controller.kicad_pcb and its schematic KiCad PCB/Luefter Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Luefter Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask PeterKirschPiano before reusing the design.
