Adafruit SHARP Memory Display Breakout - 1.3" 168x144 Monochrome
The 1.3" 168x144 SHARP Memory LCD display is a cross between an eInk (e-Paper) display and an LCD. It has the ultra-low power usage of eInk and the fast-refresh rates of an LCD. This model has a gray background, and pixels show up as black-on-gray for a nice e-Reader type display. It does not have a backlight, but it is daylight readable. For dark/night reading you may need to illuminate the LCD area with external LEDs.
The bare display is 3 Volt powered and 3 Volt logic, so we placed it on a fully assembled & tested breakout board with a 3 Volt regulator and level shifting circuitry. Now you can use it safely with 3 Volt or 5 Volt power and logic. There are four mounting holes so you can easily attach it to a box.
The 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 168x144 bits must be buffered by the microcontroller driver. That means you cannot use this with an ATmega328 or ATmega32u4. You must use a high-RAM chip such as ATSAMD21, Teensy 3, ESP8266, ESP32, etc. On those chips, this display works great and looks wonderful.
