Questions
How big is the SMT4dummies PCB?
It measures 49.5 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SMT4dummies use?
63 parts, built around the LM2902N, CD4520BE, LM555N and BC847. 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 SMT4dummies KiCad files?
From the dsquaredrobotics/SMT4dummies repository on GitHub, at the commit this page was made from: the board is PCB/SMT4dummies.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SMT4dummies 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).
