The technologies of displays have seen a lot of advancements over the past decade, and one of the most exciting developments in this regard is the E-Ink or E-Paper, that is unique in the way that is offers persistent displays – even when the power is cut. By using small pockets of ink within pressurised cells, it only needs to be powered in order to refresh or change the display. Then, once the display has been changed, it maintains the display even if the power is disconnected.

Now, with this technology becoming more accessible, we’re able to stock these 2.7inch 264x176 Three-Colour E-Ink Display HATs for Raspberry Pi Boards. These HATs use black, white and red and operate at very low power ratings, making them the ideal solution for low-power Raspberry Pi projects that need a practical, yet aesthetically appealing display.

Please Note: The background colour of this screen is white, but tends to show up as pink on camera when lighting conditions are not set up perfectly.
