Questions

How big is the FingerGrinder PCB?

It measures 90 × 55 mm and has 2 copper layers, 1.6 mm thick.

What parts does the FingerGrinder use?

34 parts, built around the ATTINY85-20PU and 74HC595. 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 FingerGrinder KiCad files?

From the raffsalvetti/FingerGrinder repository on GitHub, at the commit this page was made from: the board is board/fingergrinder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the FingerGrinder design in my own project?

Its repository states no licence, so its author keeps all rights: ask raffsalvetti before reusing the design.
