Questions
How big is the Snowman PCB?
It measures 38.1 × 58.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snowman use?
15 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 Snowman KiCad files?
From the UserHackable/Snowman repository on GitHub, at the commit this page was made from: the board is KiCad/Snowman/Snowman.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snowman design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
