Χαρακτηριστικά

E-paper display utilizes microcapsule electrophoretic technology for displaying. The principle is: charged particles suspended in clear fluid will move to sides of microcapsule when 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 e-reader due to its paper-like effect.

Features at a glance

No backlight, keeps displaying last content for a long time even when power down
Ultra low power consumption, basically power is only required for refreshing
Adapting SPI interface for connecting with controller boards like Raspberry Pi / Jetson Nano / Arduino / STM32, etc.
Onboard voltage translator, compatible with 3.3V / 5V MCUs
Comes with online development resources and manual (driver board circuit diagram, examples for Raspberry Pi / Jetson Nano / Arduino / STM32)
