eInk or ePaper wings allow you to easily connect your Feather to add eInk/ePaper support. There are two different sizes and different color variations for each size. The larger sized eInks include 3 buttons connected directly to GPIOs on the feather.

eInk is a technology that works by attracting or repelling ink droplets towards or away from the screen inside of thousands of capsules. Normally, the white pigments and the colored pigments are opposite charges. When power is removed, the pigments tend to stay in their positions and thus the last thing displayed remains. Over time though, the pigments are bound to move and you get a loss of quality unless the display is periodically refreshed.

For tri-colored and grayscale displays, the different colored pigments are actually different sizes and so they move at different speeds. By timing the attracting and repelling of the pigments correctly, you can draw in different colors. This is why it takes longer to draw with more colors.
