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.\n\nAn 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.\n\nKey Features\n\n\n250×122 Tri-Colour eInk – Black and red pixels on a white background\n\nSSD1680 Driver – SPI interface compatible with any microcontroller\n\nOnboard SRAM – Offloads the ~7.5KB frame buffer from your microcontroller\n\nUltra-Low Power – Image persists with no power; Enable pin lets you shut down SRAM, MicroSD, and display completely\n\nMicroSD Card Slot – Store images, text files, and other display content\n\n3/5V Compatible – Onboard 3.3V regulator with logic-level safe inputs\n\n\nAlso Available\n\n\n2.13\" Tri-Colour eInk FeatherWing – FeatherWing format with socket headers\n\n\nIdeal For\n\nLow-power signage with colour highlights\nE-reader and digital label projects\nBattery-powered status indicators and dashboards\nName badges, shelf tags, and price displays\n\n\nPackage Contents\n\n1× Adafruit 2.13\" Tri-Colour eInk display breakout with SRAM (assembled)\n1× Header strip\n\n\n\nNote: Tri-colour eInk displays have a longer refresh time (~15 seconds) compared to monochrome eInk. Soldering required to attach the header for breadboarding or project installation.\n\n\nSpecifications\n\n\nDisplay Size – 2.13\" diagonal\n\nResolution – 250×122 pixels\n\nColours – Tri-colour (black, red, white)\n\nDriver – SSD1680\n\nInterface – SPI\n\nLogic Level – 3.3V or 5V\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3398,"title":"Default Title","sku":"AF-4947","price":40.94,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
