Questions

What parts does the Tiny861-3 use?

23 parts, built around the LP2981-3.3. 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 Tiny861-3 KiCad files?

From the MicrochipTech/avrfreaks-projects repository on GitHub, at the commit this page was made from: the board is projects/attiny461861-rfm12-node/RFnode/Kicad_Tiny861_rfm12/tiny861-3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Tiny861-3 design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
