Questions
How big is the Ksz9031-eval PCB?
It measures 77 × 71.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ksz9031-eval use?
173 parts, built around the KSZ9031RNXCA, AZ1117EH-1.2TRG1, AZ1117EH-1.8TRG1 and AZ1117EH-2.5TRG1. 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 Ksz9031-eval KiCad files?
From the azonenberg/misc-devboards repository on GitHub, at the commit this page was made from: the board is ksz9031-eval/ksz9031-eval.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ksz9031-eval design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
