The Open Book project pairs a 4.2″ E-Ink screen with microprocessors we all know and love, building a hacker-friendly e-reader platform. Two years ago, this project won first place in our Adafruit Feather contest — the Feather footprint making the Open Book compatible with a wide range of MCUs, giving hackers choice on which CPU their hackable e-reader would run. Now, it’s time for a RP2040-based reboot.
This project is designed so that you can assemble it on your own after sourcing parts and PCBs. To help you in the process, the PCB itself resembles a book page – on the silkscreen, there is explanations of what each component is for, as well as information that would be useful for you while hacking on it, conveying the hardware backstory to the hacker about to dive into assembly with a soldering iron in hand.
So yes the AAA batteries are still adding some bulk, but it is 100% repairable at least, and there are plans to include a more compact battery. Assembly is very quick and easy, with the real challenge for many being sourcing somewhere to print the case.
