Add a large, vibrant tri-colour eInk display to your microcontroller project with this 2.7" breakout board. The panel displays red, black, and white pixels at 264×176 resolution that remain visible even with power completely disconnected — just like printed paper, but with the added impact of colour.

An onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM (~11.5 KB needed). 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

• 2.7" Tri-Colour eInk Display – 264×176 pixel resolution with red, black, and white ink
• Onboard SRAM – Offloads frame buffering from the microcontroller
• 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 – Level-shifted for safe use with any microcontroller
• CircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting

Also Available

• 2.7" Tri-Colour eInk Shield – Arduino shield form factor with user buttons

Ideal For

• Colour-coded status displays and dashboards
• Low-power signage and information boards
• Battery-powered projects requiring persistent display
• Price tags and retail displays

Package Contents
