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
- 1× Adafruit 2.13" Monochrome eInk Breakout (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.
- 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.
