Questions
How big is the Super Mini Mega Tester PCB?
It measures 99.9 × 99.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Super Mini Mega Tester use?
45 parts. 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 Super Mini Mega Tester KiCad files?
From the GadgetReboot/Super_Mini_Mega_Tester repository on GitHub, at the commit this page was made from: the board is KiCad/Super_Mini_Mega Tester.kicad_pcb and its schematic KiCad/Super_Mini_Mega Tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Super Mini Mega Tester 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).
