Questions
How big is the Buttonboard PCB?
It measures 161 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buttonboard use?
64 parts, built around the PCA9555D. 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 Buttonboard KiCad files?
From the arneman44/Mixer repository on GitHub, at the commit this page was made from: the board is Mixer PCB/kicad/mixer button board/buttonboard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buttonboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask arneman44 before reusing the design.
