Questions
How big is the Continuity tester PCB?
It measures 34.8 × 24 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Continuity tester use?
9 parts, built around the 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 Continuity tester KiCad files?
From the SHREYASHSB21/Continuity-Tester-PCB repository on GitHub, at the commit this page was made from: the board is Continuity tester.kicad_pcb and its schematic Continuity tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Continuity tester design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
