The 1.9inch Segment E-Paper Module, 91 Segments, I2C Bus offers a 1.9-inch E-Paper display.

It comes with development resources and a manual (driver board schematic, examples for Raspberry Pi/Arduino/STM32). No backlight keeps displaying the last content for a long time even when powered down.

E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in the clear fluid will move to the sides of the microcapsule when an electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
