The display is 1.44″ diagonal and 128 x 96 resolution true eInk graphical display. These are intended for use as small dynamic signage in grocery stores since a barcode displayed on it can be scanned by a laser barcode-reader. The display does not require any power to keep the image and will stay ‘on’ without any power connection for many days before slowly fading. Of course, its also daylight readable and is very high contrast. This makes it excellent for data-logging applications, outdoor displays, or any other ultra-low power usages
The good news is that rePaper/PDI have provided a suite of example code for Arduino UNO/Leonardo as well as the MSP430 Launchpad and also have a site with some documentation on how to wire up the displays and datasheets. However, please note: the displays are quite large pixel-wise and to dynamically write to the display requires 1.5K of RAM — more than the Arduino Uno or Leo/Launchpad can spare so for those boards, the example code only displays what is stored in a 8-pin FLASH chip in the devboard. (By default that FLASH contains a picture of a cat and some imaged text, see photos above)
If you want to draw ‘dynamically’ (lines, circles, text, etc) you will need an Arduino Mega (Due not tested at this time. Check our tutorial for information on how to wire to a Mega so that you can use the Adafruit GFX library for drawing.
