The larger display area and higher resolution make it ideal for detailed information displays, showing crisp black pixels on a grey background with an e-reader style appearance.\n\nThe bare display is mounted on a breakout board with a 3 V regulator, 5 V boost converter, and level shifting, making it compatible with both 3 V and 5 V power and logic. Communication requires only 3 SPI pins (write-only), but the entire 400×240 pixel framebuffer (~13.5 KB) must be stored in the microcontroller's RAM.\n\nKey Features\n\n\n2.7\" 400×240 Monochrome Display – Black-on-grey, e-reader style appearance with high resolution\n\nUltra-Low Power – E-paper-like power consumption with LCD-like refresh speed\n\nDaylight Readable – No backlight, but highly visible in ambient light\n\nSPI Interface – Write-only, requires only 3 data pins\n\n3 V / 5 V Compatible – Onboard 3 V regulator, 5 V boost converter, and level shifting\n\nZIF Socket Mounting – Display connects via ZIF socket with double-sided tape adhesion\n\n4 Mounting Holes – Easy to attach to enclosures\n\n\n\nImportant: This display requires approximately 13.5 KB of RAM for the framebuffer. It is not compatible with ATmega328 (Arduino UNO) or ATmega32u4 (Feather 32u4) boards due to insufficient RAM. Use a higher-RAM board such as ATSAMD21 (Feather M0), ESP8266, ESP32, or similar.\n\n\nAlso Consider\n\n\nSHARP Memory Display 1.3\" 168×144 – Smaller version requiring only ~3 KB RAM\n\n\nIdeal For\n\nLow-power information displays and dashboards\nOutdoor-readable status panels and signage\nBattery-powered wearable or portable displays\nE-reader style interfaces with high resolution\n\n\nPackage Contents\n\n1× SHARP Memory Display Breakout (2.7\" 400×240, fully assembled)\n\n\n\nNote: This display does not have a backlight. For dark environments, external LED illumination is needed.\n\n\nResources\n\nAdafruit SHARP Memory Display Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":3891,"title":"Default Title","sku":"AF-4694","price":91.69,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
