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.

Optional for e-Paper driver board

Standard Raspberry Pi 40PIN GPIO header, compatible with Raspberry Pi series boards, Jetson Nano

* for reference only, the Raspberry Pi is NOT included.
