Questions
How big is the MarcoPoloTTLSerialTester PCB?
It measures 49.5 × 49.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MarcoPoloTTLSerialTester use?
39 parts, built around the ATTINY25-15M. 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 MarcoPoloTTLSerialTester KiCad files?
From the cellularmitosis/MarcoPoloTTLSerialTester repository on GitHub, at the commit this page was made from: the board is kicad/MarcoPoloTTLSerialTester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MarcoPoloTTLSerialTester 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).
