OPen Book: a fully open source e-book that supports all languages ​​and breaks down working principles (schematics, PCB, source code, etc.)

Open Book is an open hardware device for reading books in all languages ​​of the world. It includes a large screen and navigation buttons, as well as audio options for accessibility and ports to expand its functionality. Its fine screen printing aims to demystify Open Book's own design, breaking down for curious readers how the book works and how they can create one for themselves.
