Questions
How big is the MainTester PCB?
It measures 67.4 × 44.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MainTester use?
29 parts, built around the ULN2003. 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 MainTester KiCad files?
From the Phunkafizer/AllSerial repository on GitHub, at the commit this page was made from: the board is Main tester/MainTester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MainTester 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).
