Questions
How big is the T85opti PCB?
It measures 18.4 × 32.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the T85opti use?
8 parts, built around the ATTINY85-15M. 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 T85opti KiCad files?
From the jscrane/DevBoards repository on GitHub, at the commit this page was made from: the board is t85opti/t85opti.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the T85opti 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).
