Questions
How big is the Userport connector PCB?
It measures 30.9 × 52.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Userport connector use?
6 parts, built around the 74LVC245AD. 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 Userport connector KiCad files?
From the bitfixer/petpix_v3 repository on GitHub, at the commit this page was made from: the board is pcb/userport_connector/userport_connector.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Userport connector design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
