Questions
How big is the Usb ps2 PCB?
It measures 38.1 × 15.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb ps2 use?
16 parts, built around the ATTINY85-20PU. 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 Usb ps2 KiCad files?
From the semicontinuity/embedded repository on GitHub, at the commit this page was made from: the board is target/touchpad/hardware/usb-ps2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb ps2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask semicontinuity before reusing the design.
