README
README.mdEvereader
What is it?
It is an esp32-s3 module based e-reader with dual screens that should be easy enough for anyone to build and customize.
Why does this project exist?
There are two main reasons:
- I really wanted to make a project bigger than what i had done until now, i want to give back at least in some way to the foss community;
- I have been getting a lot into reading lately and i really wanted an e-reader, but none of them actually felt right for me, either they where too big to put in a pocket or the smaller ones just didn't fit enough content for my taste.
Why two screens?
- Why not?
- I really wanted to keep the form factor pocketable without sacrificing text on screen, so i put two!
State of developement
I am currently just ending the breadboard circuit, after that i want to start making the PCB and develop the firmware.
TO-DO list
- Finish up the breadboard circuit.
- Finish up the PCB kicad project.
- Finish up the software.
- Refine what i can.
- Add images to the readme.

Questions
How big is the Evereader PCB?
It measures 186 × 132 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Evereader use?
74 parts, built around the AP2112K-3.3, DW01A, TP4056-42-ESOP8 and FS8205A. 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 Evereader KiCad files?
From the Ezekiel0108/Evereader repository on GitHub, at the commit this page was made from: the board is kicad/evereader/evereader.kicad_pcb and its schematic kicad/evereader/evereader.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Evereader design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
