☆ INTRODUCTION
 

This is a 4.2 inch e-ink display Good Display e-paper screen with 400x300 resolution, SPI interface, and the display is capable to display images with black and white content. It supports 3s full screen update, 0.42s partial screen update, and 1.5s fast update. 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.  Your image holds indefinitely without power – put up your image, then shut down the power.
