eINK click is an adapter for connecting eINK displays, with a 24pin ribbon cable. The eINK display sold with the click can retain the image even when the power is off. The click board™ is designed to run on a 3.3V power supply. It communicates over SPI interface.
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™.
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.
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.
