Description Waveshare 2.9 inch E-Ink Display 296x128 E-Paper is a compact black and white e-paper display module built for low-power embedded display projects. It features a 2.9 inch panel with 296×128 resolution, paper-like readability, and partial refresh support, making it well suited to information panels, smart labels, portable displays, and energy-efficient user interfaces. This 2.9inch e-paper module uses an SPI interface and can be connected to Raspberry Pi, Jetson Nano, Arduino, and other controller platforms through its onboard interface. With no backlight, wide viewing angle, and extremely low refresh power demand, it is a practical choice for projects that need clear static content without continuous power consumption. Features 2.9 inch e-paper display with 296×128 resolution for sharp monochrome output. Black and white display effect with wide viewing angle and paper-like readability. Partial refresh support for faster local updates in supported black and white e-paper workflows. SPI interface for simple integration with Raspberry Pi, Jetson Nano, Arduino, and similar boards. Onboard voltage translator compatible with 3.3V / 5V MCUs. No backlight, ultra-low power operation, and persistent content after refresh. Suitable for cross-platform development with standard e-paper demo resources and tools.
