The Open Book is an open-source e-reader hardware design built around the Raspberry Pi Pico and an e-paper display, intended to be assembled by anyone with a soldering iron. The repository contains PCB design files, assembly instructions, and documentation, with companion firmware (libros) developed separately.
Use cases
- build your own open source e-reader
- read plain text ebooks on an e-ink device you soldered yourself
- hack on e-reader firmware and hardware
- escape closed reading platforms like Kindle
- learn electronics by assembling a real device
When to choose
- you want an open, hackable, self-built e-reading device
- you enjoy DIY electronics and can fabricate a custom PCB
- you value open hardware over commercial e-readers
When to avoid
- you want a polished, slim, ready-made e-reader out of the box
- you need EPUB/PDF support or LiPo charging today
- you are not comfortable soldering and ordering custom boards
