Add a vibrant tri-colour eInk display to your Feather project with this 2.9" FeatherWing. The panel displays red, black, and white pixels at 296×128 resolution that remain visible even with power completely disconnected — just like printed paper, but with the added impact of colour.
The FeatherWing is tested to work with all Adafruit Feather boards, from the ESP8266 to the M0 and beyond. An onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM. A MicroSD socket provides storage for images and text files, and three optional buttons are available for navigation when your Feather has spare pins.
Key Features
- 2.9" Tri-Colour eInk Display – 296×128 pixel resolution with red, black, and white ink
- Onboard SRAM – Offloads frame buffering from the microcontroller (~9.5 KB needed)
- MicroSD Socket – Store images, text files, and display assets
- 3 Optional Buttons – Built-in navigation buttons for Feathers with available pins
- Ultra-Low Power – Display retains image with no power draw
- No Soldering Required – Comes with socket headers; plug your Feather straight in
- Universal Feather Compatibility – Works with all Adafruit Feather boards
- CircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting
Also Available
- 2.9" Grayscale eInk FeatherWing – 4-level greyscale with faster ~1 second refresh
- 2.9" Tri-Colour eInk Breakout – Universal breakout board
Ideal For
- Colour-coded status displays and dashboards
- Low-power IoT indicators with visual priority levels
- Name badges and conference displays
- Battery-powered signage with eye-catching colour
Package Contents
- 1× Adafruit 2.9" Tri-Colour eInk FeatherWing (with socket headers)
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.
- FeatherWing
- A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- 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.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- 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.
