Questions
How big is the Ps2 PCB?
It measures 137.2 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ps2 use?
60 parts, built around the 74HC541D, 74HC32D, 74HC00D and 74HC02. 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 KiCad files?
From the scefrom/SF68 repository on GitHub, at the commit this page was made from: the board is ps2/ps2.kicad_pcb and its schematic SF68.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ps2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask scefrom before reusing the design.
