Questions
How big is the Attiny85 dev board PCB?
It measures 15.6 × 33.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Attiny85 dev board use?
22 parts, built around the ATTINY85-20PU. 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 Attiny85 dev board KiCad files?
From the SMN321/tinyDevboard repository on GitHub, at the commit this page was made from: the board is attiny85_dev_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Attiny85 dev board 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).
