Questions
How big is the Eaaeoe PCB?
It measures 73.5 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eaaeoe use?
116 parts, built around the USBLC6-2SC6, 1N5819WS, MMBT2222A and RJ45. 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 Eaaeoe KiCad files?
From the cr1tbit/eaaeoe repository on GitHub, at the commit this page was made from: the board is eaaeoe.kicad_pcb and its schematic eaaeoe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eaaeoe design in my own project?
Its repository states no licence, so its author keeps all rights: ask cr1tbit before reusing the design.
