Questions

How big is the Block RotaryEncoder PCB?

It measures 24.1 × 24.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Block RotaryEncoder use?

9 parts. 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 Block RotaryEncoder KiCad files?

From the DennisSchulmeister/ModularMusicController repository on GitHub, at the commit this page was made from: the board is PCB/Block-RotaryEncoder/KiCAD/Block-RotaryEncoder.kicad_pcb and its schematic Experiments/LCD-Board/doc/schematic/LCD-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Block RotaryEncoder design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
