You may be familiar with ePaper or eInk displays from eReaders like the Kindle. This display is the next step up with three colors instead of the classic two. The displays really do seem like paper, with easy visibility from almost any angle and even in sunlight. It also features ultra low power consumption, using under 20mA on startup and under 10mA while running. You can even unplug the display entirely without losing your image! This display does take 14 seconds to refresh, but it is ideal for applications where information is updated infrequently, like a weather station or a high tech label.
This 4.2" ePaper display uses black, white, and red pigments on a 400 by 300 pixel matrix. The board gives you everything you need to work with the ePaper display. It even includes a microSD card slot and an SRAM so you don't have to worry about running out of memory. Using our handy ePaper library, you can add images, draw basic shapes, and even put text on the display with ease.
This board supports 5V and 3.3V logic, just make sure to power the board at the logic level you use!
