Questions
How big is the E reader PCB?
It measures 24 × 96 mm and has 4 copper layers, 1.6 mm thick.
What parts does the E reader use?
68 parts, built around the ESP32-S3-WROOM-1-N8, AP2112K-3.3TRG1, MCP73831T-2ACI/OT-HXY and USBLC6-2SC6Y. 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 reader KiCad files?
From the Navkaran-handa/e-reader repository on GitHub, at the commit this page was made from: the board is ereader.kicad_pcb and its schematic batt_ic_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E reader design in my own project?
Its repository states no licence, so its author keeps all rights: ask Navkaran-handa before reusing the design.
