Questions
How big is the Dmgplus PCB?
It measures 78.5 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dmgplus use?
108 parts, built around the MCP6021-E/P, NS8002, 74LVC4245AD and XC6206P122MR. 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 Dmgplus KiCad files?
From the Spritetm/dmgplus repository on GitHub, at the commit this page was made from: the board is kicad-pcb/dmgplus.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dmgplus design in my own project?
Its repository states no licence, so its author keeps all rights: ask Spritetm before reusing the design.
