If you’ve ever fiddled around with a Kindle and been impressed with the way it only needs to be powered when changing from static image to static image, then you will be excited with the 640x384 resolution 7.5inch E-Ink display HAT for Raspberry Pi. This display is a modular HAT, meaning that it can simply plug directly into the top of a Raspberry Pi and offer an easy-to-see, persistent display for almost any project you can imagine.

The most amazing feature about these Raspberry Pi Displays is that they use very low power consumption, and are capable of maintaining a persistent display even when the power is cut. This means that it only needs to be powered when the display is changing, as it utilises pockets of “ink” that are either pulled towards the surface of the screen or pushed to the back. This way, even when the power is completely cut, the pockets of “ink” that have been pulled towards the surface are still visible.

Typical Applications for the 7.5inch E-Ink Display HAT for Raspberry Pi, 640x384:

The 640x384 resolution 7.5inch E-Ink Display HAT for Raspberry Pi is a highly functional display that can be used for a wide range of Raspberry Pi projects, and is particularly beneficial for projects requiring ultra-low power consumption. A clock that shows hours and minutes, for example, would only need to be powered once each minute in order to refresh the minute or hour value, while using no power for the remaining 59 seconds in which the display doesn’t need to be refreshed. Furthermore, the display is designed to be highly visible even without a backlight or LED, making it seem like digital paper that can be programmed or changed with a Raspberry Pi or similar MCU.
