☆ INTRODUCTION
This is a 4.2 inch color e-ink epd display with 400x300 resolution, SPI interface, and the display is capable to display images with black, white and red content. Your image holds indefinitely without power – put up your image, then shut down the power. Once these e-paper modules are updated they don't require any power and can actually be disconnected entirely and the content will remain on the display indefinitely.

We could provide front light, touch screen and other accessories for you.
