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\nThe FeatherWing is tested to work with all Adafruit Feather boards, from the ESP8266 to the M0 and beyond. An onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM. A MicroSD socket provides storage for images and text files, and three optional buttons are available for navigation when your Feather has spare pins.\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 (~9.5 KB needed)\n\nMicroSD Socket – Store images, text files, and display assets\n\n3 Optional Buttons – Built-in navigation buttons for Feathers with available pins\n\nUltra-Low Power – Display retains image with no power draw\n\nNo Soldering Required – Comes with socket headers; plug your Feather straight in\n\nUniversal Feather Compatibility – Works with all Adafruit Feather boards\n\nCircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting\n\n\nAlso Available\n\n\n2.9\" Grayscale eInk FeatherWing – 4-level greyscale with faster ~1 second refresh\n\n2.9\" Tri-Colour eInk Breakout – Universal breakout board\n\n\nIdeal For\n\nColour-coded status displays and dashboards\nLow-power IoT indicators with visual priority levels\nName badges and conference displays\nBattery-powered signage with eye-catching colour\n\n\nPackage Contents\n\n1× Adafruit 2.9\" Tri-Colour eInk FeatherWing (with socket headers)\n\n\n\nNote: Tri-colour eInk displays take approximately 15 seconds to refresh.
