2.13 inch E-paper (BRW)

Descriptions

Electronic paper, also sometimes electronic ink(E-Ink) or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper.
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.
The only drawback may be the slow refresh speed.
The E-Ink provided by the product supports BRW three colors, B stands for black, R stands for red, and W stands for white, which can be refreshed on the screen through the picture file created in advance.
