## Summary description

Waveshare 2.9" E-paper (E-Ink) touch display with 296×128 pixel resolution, black-and-white panel and SPI/I2C interfaces. Designed for use with Raspberry Pi Pico, it offers low-power bistable screen technology suitable for static images, dashboards, signage and battery-powered projects. Includes touch functionality and standard GPIO communication for embedded applications.

## Long description

The Waveshare 2.9" E-paper (E-Ink) touch display is a compact black-and-white panel with a 296×128 pixel resolution designed for integration with Raspberry Pi Pico and other microcontroller projects. The module uses bistable E-Ink technology to retain images without power, offering extremely low standby consumption. It provides both SPI and I2C interfaces plus touch functionality and standard GPIO signals to support embedded displays, measurement dashboards and battery-operated devices.
Advantages
The E-Ink panel maintains a displayed image without continuous power, which reduces energy use in static-display applications. The touch capability adds user interaction for simple menus and controls while SPI/I2C interfaces provide flexible communication options with common microcontrollers. The compact 2.9" size and monochrome rendering simplify integration into small enclosures and low-power systems. The module is suitable for projects where readability in ambient light, minimal power draw and persistent display are priorities.
Suitable for
Battery-powered sensors and data loggers requiring persistent readouts
Static signage, price tags and shelf labels
Low-power wearable and portable devices with simple UI
Embedded dashboards and status indicators for IoT prototypes
Educational projects and rapid prototyping with Raspberry Pi Pico
Key specifications
Display size: 2.9 inches diagonal
Resolution: 296 × 128 pixels
Color: black and white (monochrome)
Interface: SPI and I2C communication supported
Touch: capacitive/resistive touch (touch functionality provided)
Power: bistable E-Ink technology for ultra-low standby power
Compatibility: designed for use with Raspberry Pi Pico and similar microcontrollers
Viewing: reflective display suitable for ambient light readability
How to use
Connect the display to a Raspberry Pi Pico or compatible microcontroller using the SPI or I2C pins and the standard GPIO signals as specified in the module documentation. Install the appropriate driver/library for the display on the host controller and configure the interface mode (SPI or I2C) in software. Use the provided touch input in your application code to detect simple touch events and update the screen buffer when content changes. Because the E-Ink panel is bistable, avoid unnecessary refreshes: update the image only when the displayed content must change to conserve power and reduce refresh time.
Usage recommendations
For best results, use this display in applications that benefit from static or infrequently changing content. Minimize full-screen refreshes and employ partial updates where supported by the driver to shorten update times and reduce energy consumption. Ensure proper wiring and level compatibility with the Raspberry Pi Pico and follow the manufacturer’s software examples for touch calibration and display refresh routines.
