CrossPoint Reader is an open-source firmware project designed as a replacement for the official firmware on the Xteink X4 e-paper display reader. The project aims to provide enhanced customization and unlock the device's full potential while maintaining EPUB reading functionality. Built using PlatformIO and targeting the ESP32-C3 microcontroller, it represents a community-driven effort to open up closed e-reader ecosystems.
Background
E-paper devices like e-readers often use closed firmware systems that limit user customization and control. The Xteink X4 is an affordable e-reader device that has gained interest from open-source communities seeking to create alternative firmware solutions.
