Add a crisp, paper-like display to your microcontroller project with the Adafruit 2.13" Monochrome eInk Breakout. This 250×122 pixel black-and-white eInk panel delivers excellent daylight readability and retains its image even with power completely disconnected — just like printed paper.
An onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM. A MicroSD socket lets you store images and text files, and the board works with both 3.3V and 5V logic for broad compatibility.
Key Features
- 2.13" Monochrome eInk Display – 250×122 pixel resolution, black on white
- Onboard SRAM – Offloads frame buffering from the microcontroller (only ~7.6 KB needed)
- MicroSD Socket – Store images, text files, and display assets
- Fast Refresh – Updates in just a couple of seconds (compared to ~15 seconds for tri-colour eInk)
- 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 – Level-shifted for safe use with any microcontroller
- CircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting
Also Available
- 2.13" Monochrome eInk Bonnet – For Raspberry Pi
- 2.13" Monochrome eInk FeatherWing – For Feather boards
- 2.13" Tri-Colour eInk Breakout – Red, black, and white version
Ideal For
- Low-power IoT dashboards and sensor readouts
- Portable information displays
- Name badges and signage
- Battery-powered projects requiring persistent display
Package Contents

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.
- 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.
- 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 single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- RAM
- RAM (random-access memory) is fast, temporary memory a device uses for working data while it is running; in its common volatile form, its contents are lost when power is removed. Some devices offer a mode that applies settings to RAM only, which is handy for testing changes temporarily because they are not stored permanently and disappear at power-off.
- 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.
