Want to take your Raspberry Pi project to the next level? This large 2-colour, low-power, 7.5-inch e-Paper E-Ink Display will definitely add a cool factor to your project that only E-Ink displays can! Not only will it look cool, but as with all E-Ink displays, your project will consume less power than it would with a typical LCD. This is a 2-colour display (black and white) and features a resolution of 880 x 528 pixels.

E-paper display utilizes microcapsule electrophoretic technology to display text and images. E-Ink displays work by applying an electrical charge to tiny coloured particles that are suspended in a clear fluid which move to different sides of a microcapsule when an electric field is applied. This causes the microcapsule to become visible by reflecting ambient light, giving it that printed paper-like feel. Another advantage of E-Ink displays is that they feature nearly up to 180° viewing angle. This display is what you would find in a typical e-reader due to its paper-like effect, and does require an external light source such as a lamp or daylight to view.

Online development resources are available, which include wiring guidance and example code, with additional information being found on the Waveshare Wiki.
