Advantages of EINK
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.
Raspberry Pi Pico header compatibility
onboard female pin header for direct attaching to Raspberry Pi Pico2x user buttons and 1x reset button for easy interacting
Stackable design
extended Pico header, allows attaching more modules for Pico
Widely compatible driver board
Onboard switch for using with multi e-paper displays, or selecting SPI bus
