The Adafruit 2.13" Tri-Colour eInk Display brings electronic paper technology to your microcontroller projects. Featuring a 250×122 pixel display with black, red, and white ink, 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 two-colour frame buffer (~7.5KB for black + red layers) from your microcontroller's memory, sharing the same SPI bus as the display with just one extra pin. Compose your image in SRAM and transfer it to the eInk panel when ready, keeping your microcontroller's RAM free for other tasks. The SSD1680 driver provides reliable control over the display.

Key Features

• 250×122 Tri-Colour eInk – Black and red pixels on a white background
• SSD1680 Driver – SPI interface compatible with any microcontroller
• Onboard SRAM – Offloads the ~7.5KB frame buffer from your microcontroller
• Ultra-Low Power – Image persists with no power; Enable pin lets you shut down SRAM, MicroSD, and display completely
• MicroSD Card Slot – Store images, text files, and other display content
• 3/5V Compatible – Onboard 3.3V regulator with logic-level safe inputs
