Questions
How big is the Minivol led encoder PCB?
It measures 66 × 57.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Minivol led encoder use?
26 parts, built around the 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 Minivol led encoder KiCad files?
From the gregose/minivol repository on GitHub, at the commit this page was made from: the board is pcb/minivol_led_encoder/minivol_led_encoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Minivol led encoder design in my own project?
Its repository states no licence, so its author keeps all rights: ask gregose before reusing the design.
