Questions
How big is the Ksz9563 lan7800 switch PCB?
It measures 175 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ksz9563 lan7800 switch use?
48 parts, built around the KSZ9563RNXC and LAN7800/Y9X. 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 Ksz9563 lan7800 switch KiCad files?
From the flannellab/AI_Design_Generation repository on GitHub, at the commit this page was made from: the board is ksz9563_lan7800_switch/ksz9563_lan7800_switch.kicad_pcb and its schematic ksz9563_lan7800_switch/ksz9563_lan7800_switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ksz9563 lan7800 switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask flannellab before reusing the design.
