Questions
How big is the Soundboard PCB?
It measures 105 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Soundboard use?
53 parts, built around the TLC59283DBQ, ASMB-MTB1-0A3A2 and IRLML6401. 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 Soundboard KiCad files?
From the chill389cc/Soundboard repository on GitHub, at the commit this page was made from: the board is CAD/Soundboard/Soundboard.kicad_pcb and its schematic CAD/Soundboard/Soundboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Soundboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask chill389cc before reusing the design.
