Questions
How big is the Smart Knob PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Smart Knob use?
75 parts, built around the TXU0101 and IN-PI42TASPRPGPB. 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 Smart Knob KiCad files?
From the danielzyy/Smart_Knob repository on GitHub, at the commit this page was made from: the board is Electrical/smart_knob.kicad_pcb and its schematic Electrical/smart_knob.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart Knob design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
