Questions
How big is the Eclipse PCB?
It measures 357.2 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eclipse use?
209 parts, built around the AO3400A. 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 Eclipse KiCad files?
From the arnstadm/eclipsepcb repository on GitHub, at the commit this page was made from: the board is pcb files/eclipse.kicad_pcb and its schematic pcb files/eclipse.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eclipse design in my own project?
Its repository states no licence, so its author keeps all rights: ask arnstadm before reusing the design.
