Questions
How big is the PS2-breakout PCB?
It measures 33 × 43.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PS2-breakout use?
34 parts, built around the MD-60SM, RCLAMP0502A and MMBF170. 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 PS2-breakout KiCad files?
From the jedp/PS2-breakout repository on GitHub, at the commit this page was made from: the board is ps2-breakout.kicad_pcb and its schematic ps2-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PS2-breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask jedp before reusing the design.
