Overview
The 1.3" 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 matt silver background, and pixels show up
as little mirrors for a silver-reflective display, a really beautiful and unique look. 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 display is 3V powered and 3V logic, so we placed it on a fully assembled & tested breakout board with a 3V
regulator and level shifting circuitry. The display slots into a ZIF socket on board and we use a piece of double-sided
tape to adhere it onto one side. 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. The downside of a write-only display is
that the entire memory must be buffered by the microcontroller driver.
If you have one of the older 96x96 pixel versions, then 96x96 bits = 1,152 bytes. On an Arduino Uno/Leonardo that's
half the RAM available and so it might not be possible to run this display with other RAM-heavy libraries like SD
interfacing.
If you have one of the newer 168x144 pixel versions, then 168x144 bits = 3,024 bytes. That won't fit on an Arduino Uno
or Leonardo! You must use a chip with more RAM like a Metro or Feather M0 or ESP8266.
The Sharp Memory Display breakout board ships with optional headers for use in a breadboard.

Assembly and Wiring
The display and support circuitry come pre-assembled and fully tested on a handy breakout board. For use in a
breadboard, you will want to install the included 0.1" header strip:
Installing the Header:
Position the header
Trim the header to length if necessary and place it long
pins down in your breadboard.
Position the display
Place the Sharp Memory Display over the pins on the
breadboard.
Solder!
Solder each pin to assure good electrical conductivity.
