특징

eINK displays

The display uses electronic ink, which makes the display "Bistable". It means that the display consumes power only when something is changing on the screen. This reduces the power consumption of the target device considerably. So, the display retains the image even when the power is off.

eINK displays have good sunlight readability, it's like you are reading something on real paper. It is the same type of display used in you ebook reader, like the Kindle™.

How the click works

The display communicates with the eINK click over SPI interface. The onboard LM75 temperature sensor is used for temperature calibration from the look-up table.

The click can be used with different eINK displays we plan to release in the future.

Display features

The eINK display (EA EPA20-A) is a high-contrast e-paper display. It has a wide viewing angle and the resolution of 172X72 dots. The color of the display has four scales: black, dark gray, light gray, and white.

The power consumption, while the display is on, is around 40mW.
