Questions
What parts does the Analog keeb proto use?
150 parts, built around the RP2040, W25Q128JVSIQ, CD74HC4067SM96 and SRV05-4. 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 Analog keeb proto KiCad files?
From the tofy-dev/analog-prototype repository on GitHub, at the commit this page was made from: the board is analog-keeb-proto.kicad_pcb and its schematic analog-keeb-proto.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Analog keeb proto design in my own project?
Its repository states no licence, so its author keeps all rights: ask tofy-dev before reusing the design.
