The Adafruit SHARP Memory Display Breakout features a 2.7" 400×240 monochrome LCD that combines the ultra-low power consumption of e-paper with the fast refresh rates of a traditional LCD. 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.

The 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.
