At 2.13" diagonal and 122x250 resolution, this ePaper display supports detailed images. One huge benefit of ePaper displays is that they are bi-stable- which means once an image is set on the display does not require any power to hold it there.
This ePaper is black and white monochrome and supports partial updates in addition to full display updates. That makes it a great choice for showing data where one part updates more quickly than others. Keep in mind that an update takes around 3 seconds.
Because ePaper displays hold images without using power, they are great choices for solar or battery-powered projects. If the refresh time on an ePaper makes it unsuitable, check out this list of low-power displays.
Black and white monochrome
Bistable (Will continue to display with no power source)

Sample code and datasheet can be found in the Datasheets & Files section.
The sample sketch is written for a Seeeduino which is a 3.3v version of the popular Arduino Uno hardware. A development kit for this display is available and includes the Seeeduino and adapter board.
