The Waveshare 4.37inch E-Paper Module (G), 512x368, Red/Yellow/Black/White 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. Onboard voltage translator, compatible with 3.3V/5V MCUs.

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.

E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as an e-reader due to its paper-like effect.
