Questions
What parts does the DnD20 use?
38 parts, built around the CP2104EK and MMA8653FCR1. 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 DnD20 KiCad files?
From the MatthewCLind/DnD20 repository on GitHub, at the commit this page was made from: the board is ECAD/DnD20/DnD20.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DnD20 design in my own project?
Its repository states no licence, so its author keeps all rights: ask MatthewCLind before reusing the design.
