This is an E-Ink raw display, 1.54inch, 200x200 resolution. Of course, you will need an embedded controller to make it works :) It communicates via SPI interface, supports partial refresh and it is monochrome, only black and white, simple yet practical!
Due to the advantages like ultra-low power consumption, wide viewing angle, clear display without electricity, it is an ideal choice for applications such as shelf labels, industrial instruments, and so on.
