2.9-Inch Black & White E-Ink Display Module (SPI & I2C Interface)

The 2.9-inch Black & White E-Ink Display Module is a high-performance electronic paper display solution designed for ultra-low power embedded applications. Featuring a true paper-like visual experience, this display delivers exceptional readability under both indoor lighting and direct sunlight conditions, without the need for a backlight.

With support for both SPI and I2C communication interfaces, the module offers flexible system integration options, making it suitable for a wide range of microcontroller platforms and IoT devices.

Product Overview

This 2.9-inch monochrome e-paper display provides sharp black-and-white contrast with a resolution of 296 × 128 pixels. It consumes power only during image refreshing and retains the displayed content even when power is removed, making it ideal for battery-powered and energy-sensitive applications.

Unlike traditional LCD or TFT displays, the E-ink technology reflects ambient light instead of emitting light, significantly reducing eye strain and improving outdoor visibility.
