Questions
How big is the ETH1LCR3 PCB?
It measures 160 × 100 mm and has 6 copper layers, 1.6 mm thick.
What parts does the ETH1LCR3 use?
546 parts, built around the SN74LV1T34DBV, AD8099ARDZ, LMH6644MT and LMH6720MF. 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 ETH1LCR3 KiCad files?
From the BehrensG/ETH1LCR3 repository on GitHub, at the commit this page was made from: the board is Hardware/ETH1LCR3/ETH1LCR3.kicad_pcb and its schematic Hardware/ETH1LCR3/Connector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ETH1LCR3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BehrensG before reusing the design.
