Questions
How big is the EOGlass PCB?
It measures 25 × 11 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EOGlass use?
46 parts, built around the AD8226ARMZ, LMV324, MCP41010-E/P 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 EOGlass KiCad files?
From the xinterface/EOGee repository on GitHub, at the commit this page was made from: the board is EOGlass1/EOGlass.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EOGlass design in my own project?
Its repository states no licence, so its author keeps all rights: ask xinterface before reusing the design.
