Add a large, vibrant tri-colour eInk display to your Arduino project with this shield. The 2.7" panel displays red, black, and white pixels at 264×176 resolution that remain visible even with power completely disconnected. The shield form factor plugs directly onto Arduino-compatible boards from the ATmega328 up to the ATSAMD51.
Four user buttons (A, B, C, D) on the front face share a single analogue pin (A3), giving you menu navigation and input without using extra GPIO. An onboard SRAM chip handles frame buffering, and a MicroSD socket provides storage for images and text files.
Key Features
- 2.7" Tri-Colour eInk Display – 264×176 pixel resolution with red, black, and white ink
- Arduino Shield Form Factor – Plugs directly onto Arduino-compatible boards
- 4 User Buttons – Labelled A, B, C, D; all read via a single analogue pin (A3)
- Onboard SRAM – Offloads frame buffering from the microcontroller (~11.5 KB needed)
- MicroSD Socket – Store images, text files, and display assets
- Ultra-Low Power – Display retains image with no power draw; Enable pin lets you shut down SRAM, MicroSD, and display entirely
- 3.3V and 5V Compatible – Works with any Arduino-compatible board
- CircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting
Also Available
- 2.7" Tri-Colour eInk Breakout – Universal breakout board
Ideal For
- Arduino-based dashboards and status displays
- Low-power signage and information boards
- Interactive menu systems with button navigation
- Battery-powered projects requiring persistent display
Package Contents
- 1× Adafruit 2.7" Tri-Colour eInk Shield (with header strip)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- CircuitPython
- A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SRAM
- Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.
