{"title":"Adafruit 2.7 Tri-Color eInk / ePaper Shield with SRAM - Red Black White","handle":"adafruit-2-7-tri-color-eink-epaper-shield-with-sram-red-black-white","url":"/products/adafruit-2-7-tri-color-eink-epaper-shield-with-sram-red-black-white","description":"Add a large, vibrant tri-colour eInk display to your Arduino project with this shield. The 2.7\" panel displays red, black, and white pixels at 264×176 resolution that remain visible even with power completely disconnected. The shield form factor plugs directly onto Arduino-compatible boards from the ATmega328 up to the ATSAMD51.\n\nFour user buttons (A, B, C, D) on the front face share a single analogue pin (A3), giving you menu navigation and input without using extra GPIO. An onboard SRAM chip handles frame buffering, and a MicroSD socket provides storage for images and text files.\n\nKey Features\n\n\n2.7\" Tri-Colour eInk Display – 264×176 pixel resolution with red, black, and white ink\n\nArduino Shield Form Factor – Plugs directly onto Arduino-compatible boards\n\n4 User Buttons – Labelled A, B, C, D; all read via a single analogue pin (A3)\n\nOnboard SRAM – Offloads frame buffering from the microcontroller (~11.5 KB needed)\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 – Works with any Arduino-compatible board\n\nCircuitPython and Arduino Support – Adafruit_GFX compatible library handles all the heavy lifting\n\n\nAlso Available\n\n\n2.7\" Tri-Colour eInk Breakout – Universal breakout board\n\n\nIdeal For\n\nArduino-based dashboards and status displays\nLow-power signage and information boards\nInteractive menu systems with button navigation\nBattery-powered projects requiring persistent display\n\n\nPackage Contents\n\n1× Adafruit 2.7\" Tri-Colour eInk Shield (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.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":5286,"title":"Default Title","sku":"AF-4229","price":77.94,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
