This is 2.13inch Electronic paper, also sometimes electronic ink(E-Ink) or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper.
Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi 4B/3B+/3B/2B/Zero/Zero W/Zero WH
250×122 resolution, with embedded controller, communicating via SPI interface, supports partial refresh.
Electrodes located above and below the capsules move up and down when a positive or negative electric field is applied, which makes the surface of the electronic paper display reflect a certain color. The consumption of E-ink is very low during operation.
Once the data is refreshed on the screen, it can be kept for a long time without power consumption. It is very suitable for displaying some specific information for a long time.
