The Adafruit 1.54" Monochrome eInk Display brings electronic paper technology to your microcontroller projects. Featuring a 200×200 pixel black-and-white display, this breakout delivers high-contrast, daylight-readable visuals that persist even when power is completely disconnected — just like printed paper.

An onboard SRAM chip offloads the frame buffer from your microcontroller's memory, sharing the same SPI bus as the display with just one extra pin. This means you can compose your image in SRAM and transfer it to the eInk panel when ready, keeping your microcontroller's RAM free for other tasks.

Key Features

• 200×200 Monochrome eInk – High-contrast black pixels on a white background
• Onboard SRAM – Offloads frame buffer so your microcontroller doesn't need 8KB of spare RAM
• Ultra-Low Power – Image persists with no power; Enable pin lets you shut down SRAM and display completely
• Fast Refresh – Updates in a couple of seconds (much faster than tri-colour eInk displays)
• MicroSD Card Slot – Store images, text files, and other display content
• 3/5V Compatible – Onboard 3.3V regulator with logic-level safe inputs
• SPI Interface – Works with any microcontroller platform

Also Available

• 1.54" Tri-Colour eInk (Black/Red/White) – 200×200

Ideal For
