Questions
How big is the EOGee PCB?
It measures 74.3 × 11.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EOGee use?
48 parts, built around the AD8226ARMZ, LMV324 and BK0603HS330-T. 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 EOGee KiCad files?
From the xinterface/EOGee repository on GitHub, at the commit this page was made from: the board is EOGee1/EOGee.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EOGee design in my own project?
Its repository states no licence, so its author keeps all rights: ask xinterface before reusing the design.
