Overview
Attiny85-breakout is an open-source printed circuit board by AaronC81, from the AaronC81/attiny-breakout repository on GitHub. It is a 2-layer board of 22.9 × 21.6 mm with 4 parts on 8 nets, routed with 27 tracks and 0 vias.
It is built around the ATTINY85-20PU. Its parts include 3 connectors and 1 IC. It belongs with the interfaces and adapters boards and the AVR (ATmega, ATtiny) boards of this library.
Main components
1README
README.mdATtiny Breakout
This is a little breakout board for easy programming of DIP ATtiny25/45/85 chips on a breadboard.
(I got mine fabricated by JLC, which worked out at about £5.50 for five boards, including delivery.)
It has a 6-pin ISP header for programming, so you'll need an AVR programmer. It also passes the ATtiny's pins through headers on the bottom of the board; this means you can plug it straight into a breadboard, and once you're done programming your ATtiny, simply remove the breakout and replace it with the lone chip.
It's been tested with an ATtiny85 (but should work on 25 and 45 too) and a Pololu USB AVR Programmer.

Questions
How big is the Attiny85-breakout PCB?
It measures 22.9 × 21.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Attiny85-breakout use?
4 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-breakout KiCad files?
From the AaronC81/attiny-breakout repository on GitHub, at the commit this page was made from: the board is attiny85-breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Attiny85-breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask AaronC81 before reusing the design.
