Questions
How big is the RJ45 PCB?
It measures 19.1 × 34.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RJ45 use?
3 parts. 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 RJ45 KiCad files?
From the mignon-p/EthernetBreakout repository on GitHub, at the commit this page was made from: the board is RJ45.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RJ45 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
