It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a gray background, and the pixels show up as black-on-gray for a nice e-reader type display. It does not have a backlight, but it \u003cem\u003eis\u003c\/em\u003e daylight readable. For dark\/nighttime reading you may need to illuminate the LCD area with external LEDs.\u003c\/p\u003e\u003cp\u003eThe bare display is 5V powered and 3V logic, so we placed it on a fully assembled-and-tested breakout board with both a 3V regulator, 5V boost converter, and level shifting circuitry. Now you can use it safely with 3 \u003cem\u003eor\u003c\/em\u003e 5V power and logic. The bare display slots into a ZIF socket on board, and we use a piece of double-sided tape to adhere it. Comes with four mounting holes so you can easily attach it to your project.\u003c\/p\u003e\u003cp\u003eThe display is 'write only' which means that it only needs 3 pins to send data. However, the downside of a write-only display is that the entire 400x240 bits (13.5 KB) must be buffered by the microcontroller driver. \u003cstrong\u003eThat means you cannot use this with an ATmega328 (e.g. Arduino UNO) or ATmega32u4 (Feather 32u4, etc).\u003c\/strong\u003e You must use a high-RAM chip such as ATSAMD21 (Feather M0), Teensy, ESP8266, ESP32, etc. On those chips, this display works great and looks fantastic.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note, the animation of the display showing the Bad Apple demo is scaled up\u003c\/strong\u003e which is why it looks blocky, the animation is there to show you the contrast and refresh not resolution!\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCheck our our detailed guide for wiring diagrams, schematics, libraries, code, Fritzing objects, etc!\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\u003cdiv class=\"row\"\u003e\u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\u003cul\u003e\n\u003cli\u003eDisplay dimensions (viewable): 58.8mm × 35.3mm\u003c\/li\u003e\n\u003cli\u003eDot pitch: 0.147 mm (square)\u003c\/li\u003e\n\u003cli\u003eDisplay size: 6.86 cm \/ 2.7\" diagonal\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e\u003c\/div\u003e\u003c\/div\u003e \u003c\/div\u003e\n\u003cul id=\"product-files\"\u003e \u003c\/ul\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"col-lg-2 col-md-3 col-sm-3 col-xs-4\"\u003e\u003c\/div\u003e\n\u003c\/div\u003e \u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":52217495585056,"sku":"nsw1787258158730","price":26.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0946\/3231\/3120\/files\/adafruit-sharp-memory-display-breakout---27-400x240-monochrome_1.jpg?v=1787258163","url":"https:\/\/www.elmwoodbasket.shop\/products\/adafruit-sharp-memory-display-breakout-27-400x240-monochrome","provider":"My Store","version":"1.0","type":"link"}
