Questions
What parts does the Simple Curve Tracer use?
36 parts, built around the LM358, 74LS393P-E, NE555P 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 Simple Curve Tracer KiCad files?
From the jakeson21/Small-KiCAD-Projects repository on GitHub, at the commit this page was made from: the board is Simple_Curve_Tracer/Simple_Curve_Tracer.kicad_pcb and its schematic Dual_Sticks_With_Buttons/Dual_Sticks_With_Buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simple Curve Tracer design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
