## Summary description

3.7-inch Waveshare E-paper (E-Ink) display with 480×280 pixel resolution, monochrome (black and white) panel and SPI interface.

Suitable for e-readers, status panels, low-power indicators and embedded projects.

## Long description

The 3.7-inch Waveshare E-paper (E-Ink) display offers a 480×280 monochrome (black and white) panel with an SPI interface, designed for integration with Raspberry Pi Pico and similar microcontroller boards. The module uses electronic ink technology to hold static images without continuous power, providing clear, paper-like contrast in ambient light and supporting partial refresh for selective updates. Its compact form factor and low-power characteristics make it suitable for battery-powered and always-on display applications.
Advantages
This E-Ink display consumes minimal power when showing a static image, enabling extended operation on battery-powered systems. The 480×280 resolution provides sufficient detail for text, icons and simple graphics while the monochrome panel delivers high legibility in a wide range of lighting conditions. The SPI interface and compatibility with Raspberry Pi Pico simplify hardware connection and software integration for embedded projects. Partial refresh capability reduces update time and power for small screen changes.
Suitable for
E-readers and electronic paper interfaces
Status panels and information displays
Low-power indicators and battery-operated devices
Embedded projects and prototypes with Raspberry Pi Pico or similar MCUs
Static signage and price tags
Key specifications

Resolution: 480 × 280 pixels
Color: monochrome (black and white)
Interface: SPI (serial peripheral interface)
Refresh modes: full refresh and partial refresh supported
Display type: E-paper / E-Ink
Reading characteristic: reflective, readable in ambient light
Typical use: low-power, static image retention
How to use
Connect the module to a Raspberry Pi Pico or a compatible microcontroller via the SPI pins, power and ground. Follow the manufacturer's wiring and voltage recommendations to ensure reliable operation. Install the appropriate driver/library for Waveshare E-paper displays on your development environment and use provided example code to initialize the display, draw text or graphics, and perform full or partial updates. For battery-powered systems, update the screen only when content changes to preserve power; keep the device in low-power or sleep modes between updates.
Usage recommendations
Use full refresh periodically to avoid image ghosting after many partial updates, and operate the display within recommended voltage and temperature ranges. For best legibility, design monochrome graphics with sufficient contrast and avoid very fine details that may not render clearly at 480×280 resolution.
