Questions
What parts does the TransistorCurveTracer use?
57 parts, built around the NE555P and BC547. 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 TransistorCurveTracer KiCad files?
From the erichardy/Misc-Electronic-Projects repository on GitHub, at the commit this page was made from: the board is TransistorCurveTracer/TransistorCurveTracer.kicad_pcb and its schematic SimpleTransistorCurveTracer/Module1/Module1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TransistorCurveTracer 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).
