E-Ink and ePaper panels are ideal for low-power projects where you want a daylight-readable display that keeps showing its image even when power is removed. This bare 2.66 inch panel gives you a crisp, paper-like monochrome display for DIY eInk builds.
This is the display element only, so it needs to be connected to a board with a standard 24-pin FPC e-paper connector. Adafruit recommends using a matching driver board such as the Feather RP2040 ThinkInk, eInk Feather Friend, eInk Breakout Friend, or a 24-pin eInk/ePaper extension cable with 24-pin FPC adapter.
The panel uses the SSD1680 chipset, so make sure your firmware supports it. Adafruit’s Arduino library handles the display control for you and lets you use it like an Adafruit_GFX compatible display.
You can also put the display into an unofficial “4-gray” mode for two extra monochromatic shades. It is not officially supported by the display, but can be useful with dithering for better-looking output.

A good choice for custom low-power signage, labels, status displays and other projects where the image only needs to update occasionally.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- ePaper
- A display technology that looks more like printed paper than a glowing screen and usually keeps its image visible with very little power. It matters for projects such as labels, badges, and status screens where readability and low power use are more important than fast animation.
- FPC
- FPC stands for flexible printed circuit, a thin flat flexible cable or connector style often used where space is tight or some movement is needed, commonly for displays, cameras and other high-density connections. Connecting to an FPC connector generally needs a matching cable with the correct pin count, pitch and contact orientation.
- RP2040
- The RP2040 is a dual-core Arm Cortex-M0+ microcontroller chip from Raspberry Pi, used on many maker boards and offering programmable I/O, multiple GPIO pins and reasonable processing speed. Code and accessories built for that chip should work where RP2040 compatibility is listed, though demanding tasks such as reading a camera can require careful pin allocation and timing.
