Questions
What parts does the PS2Addon use?
82 parts, built around the RP2354A, 74LS125DC, USBLC6-2P6 and AP2112K-3.3. 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 PS2Addon KiCad files?
From the MicroLind-Developers/microlind-hw repository on GitHub, at the commit this page was made from: the board is peripherals/WIP/PS2Addon/PS2Addon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PS2Addon design in my own project?
Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
