2.13-inch E-Paper for Raspberry Pi Pico

This 2.13-inch E-Ink display module connects to a Raspberry Pi Pico via SPI. It shows red, black and white pixels at 212×104 resolution. The paper-like screen needs no backlight and holds its image without power. Developers building low-power signage, badges or sensor read-outs will find it a direct fit.

SPI interface limits refresh speed and wiring

The SPI bus needs only a few GPIO pins, leaving the rest free for sensors or radios. E-Ink technology updates slowly, so full-screen changes take seconds and partial refresh is not supported. Continuous animation or video playback is not practical. The panel draws measurable current only during a refresh cycle.

Three-colour 212×104 resolution decides suitability

The 212×104 pixel grid in red, black and white sets the amount of text or graphics that fit legibly. Projects needing higher pixel density, greyscale levels or faster update rates must choose a different panel. This module matches applications where the exact resolution and tri-colour palette meet the design brief.

Questions about this item

Should I choose the 212×104 pixel version or a different resolution?

This module is the 212×104 pixel version; no other resolution is offered for this 2.13inch model.

What does the 212×104 pixel count mean when the display is running in a project?

It gives a 2.13inch active area with red, black and white pixels, retaining the last image without power and drawing current only during refresh.

How does the SPI interface limit the display in practice?

SPI uses few GPIO pins on the Raspberry Pi Pico, keeping wiring simple while the refresh speed is set by the e-paper panel's own timing.
