Ideal for battery-powered indicators, e-readers, price tags, and status displays where retained image without power is required.

## Long description

Waveshare E-paper E-Ink 2.9" 296×128 px is a black-and-white flexible display module designed as an add-on for Raspberry Pi Pico. The module offers a 296×128 pixel monochrome e-ink panel that retains images without power, making it suitable for low-power and battery-operated projects that require static images, text or simple graphics. The display is intended for applications such as e-readers, price tags, status indicators and information panels where long-term image retention and minimal energy consumption are important.
Advantages
The e-ink technology provides bistable image retention so the last displayed content remains visible with no supply current. The monochrome panel supports clear text and simple graphics with wide viewing angles and low reflectivity. Designed to interface with Raspberry Pi Pico, the module integrates into microcontroller projects for battery-powered or always-on indicators. The thin, flexible form factor reduces weight and space requirements compared with conventional LCDs, and the low average power consumption extends battery life in portable setups.
Suitable for
Battery-powered information displays and indicators
Price tags and shelf labels with infrequent updates
Simple e-reader or document display projects
Status dashboards, sensor readouts and IoT endpoints
Low-power signage and static graphic panels
Key specifications
Display type: monochrome e-ink (black/white)
Diagonal size: 2.9 inches
Resolution: 296 × 128 pixels
Viewing: wide viewing angles with low reflectivity
Power characteristic: bistable display—image retained without power
Interface: compatible with Raspberry Pi Pico add-on connections
Physical: thin, lightweight and flexible panel suitable for embedded projects
How to use
Connect the module to a Raspberry Pi Pico following the manufacturer's pinout and wiring guidelines for the display interface. Use the provided or available driver libraries and example code to initialize the e-ink controller, clear the panel and send monochrome image or text buffers at the native resolution of 296 × 128 pixels. Update the screen only when necessary to conserve power; the e-ink panel will retain the displayed image after the Pico and module are powered down. Allow full refresh and partial update timings as recommended by the driver to ensure correct contrast and minimize ghosting.
Usage recommendations
For best results, use the module in applications with infrequent screen changes. Prepare monochrome image assets at the native resolution to avoid scaling artifacts, and follow driver timing and refresh guidance to reduce visual ghosting. When operating from batteries, schedule display updates and put the host microcontroller into low-power modes between updates to maximize runtime.
