Adafruit 2.13 Tri-Color eInk / ePaper Display with SRAM - Red Black White

Add a vibrant tri-colour eInk display to your microcontroller project with this breakout board. The 2.13" panel displays red, black, and white pixels 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. 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" Tri-Colour eInk Display – 212×104 pixel resolution with red, black, and white ink
• Onboard SRAM – Offloads frame buffering from the microcontroller (only ~5.5 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 – 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" Tri-Colour eInk FeatherWing – For Feather boards
• 2.13" HD Tri-Colour eInk FeatherWing – Higher resolution 250×122 version
• 2.13" Monochrome eInk Breakout – Faster-refreshing black and white version (250×122)

Ideal For

• Colour-coded status displays and dashboards
• Low-power IoT indicators with visual priority levels
• Portable signage with eye-catching colour
• Battery-powered projects requiring persistent display
