Questions
How big is the MOS6581Board PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MOS6581Board use?
52 parts, built around the ATMEGA2560-16AU and 6N138SM. 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 MOS6581Board KiCad files?
From the dandandrea/MOS6581-PCB repository on GitHub, at the commit this page was made from: the board is Synth-Board/MOS6581Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MOS6581Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask dandandrea before reusing the design.
