{"title":"Adafruit 2.9 Red/Black/White eInk Display Breakout - THINK INK","handle":"adafruit-2-9-red-black-white-eink-display-breakout-think-ink","url":"/products/adafruit-2-9-red-black-white-eink-display-breakout-think-ink","description":"Add a large, vibrant tri-colour eInk display to your microcontroller project with this 2.9\" breakout board. The panel displays red, black, and white pixels at 296×128 resolution that remain visible even with power completely disconnected — just like printed paper, but with the added impact of colour.\n\nAn onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM (~9.5 KB needed). A MicroSD socket provides storage for images and text files, and the board works with both 3.3V and 5V logic for broad compatibility.\n\nKey Features\n\n\n2.9\" Tri-Colour eInk Display – 296×128 pixel resolution with red, black, and white ink\n\nOnboard SRAM – Offloads frame buffering from the microcontroller\n\nMicroSD Socket – Store images, text files, and display assets\n\nUltra-Low Power – Display retains image with no power draw; Enable pin lets you shut down SRAM, MicroSD, and display entirely\n\n3.3V and 5V Compatible – Level-shifted for safe use with any microcontroller\n\nCircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting\n\n\nAlso Available\n\n\n2.9\" Tri-Colour eInk FeatherWing – For Feather boards with buttons\n\n2.9\" Grayscale eInk FeatherWing – 4-level greyscale with faster refresh\n\n\nIdeal For\n\nColour-coded status displays and dashboards\nLow-power signage and information boards\nPrice tags and retail displays\nBattery-powered projects requiring persistent display\n\n\nPackage Contents\n\n1× Adafruit 2.9\" Tri-Colour eInk Breakout (with header strip)\n\n\n\nNote: Soldering is required to attach the included header. Tri-colour eInk displays take approximately 15 seconds to refresh. For faster updates, consider the grayscale version which refreshes in about 1 second.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4875,"title":"Default Title","sku":"AF-1028","price":68.19,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":28,"option1":"Default Title"}]}
