a e-reader... aka chapri kindle So my projects basically a e-reader like a kindle but a lot bulkier, and it uses a 4-3inch e-paper display, an esp32 s3, 3 2000mah li-ion batteries, it also uses 2 TOF VL53LOX sensors for swipe movements for swiping pages or changing the content displayed on the screen, I used kicad to make the pcb which connects all th parts and fusion 360 for the 3d printed chassis

Questions
How big is the E reeder PCB?
It measures 121.5 × 119.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E reeder use?
6 parts. 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 E reeder KiCad files?
From the HaYm2011/e-reeder repository on GitHub, at the commit this page was made from: the board is PCB_files/e-reeder.kicad_pcb and its schematic PCB_files/e-reeder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E reeder design in my own project?
Its repository states no licence, so its author keeps all rights: ask HaYm2011 before reusing the design.
