Questions
How big is the KeyModule R PCB?
It measures 195 × 148 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KeyModule R use?
110 parts, built around the MCP23017-E/SS and RJ45. 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 KeyModule R KiCad files?
From the cho45/Keble repository on GitHub, at the commit this page was made from: the board is KeyModule-R.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the KeyModule R design in my own project?
Its repository states no licence, so its author keeps all rights: ask cho45 before reusing the design.
