Questions
How big is the Dev board PCB?
It measures 22 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board use?
5 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 Dev board KiCad files?
From the PhysicsUofRAUI/kodysAvrPrograms repository on GitHub, at the commit this page was made from: the board is attiny85_programs/dev_board/dev_board.kicad_pcb and its schematic attiny85_programs/dev_board/dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board 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).
