This module is high contrast, wide viewing angle triple-color e ink Display for Raspberry Pi. The e-ink screen can customize the picture when it is powered on, the picture will not disappear after power off, and it can be displayed for a long time. The display area of this module is 2.7 inches which contains 264x176 pixels. Each pixel can display red, white and black.
E-ink screen also known as E-paper screen has lots of advantages compared with traditional backlight display like LCDs. It can display images or words like paper, even without any electricity, the image can last in a long time. Since it does not require a backlight, it can be clearly displayed in direct sunlight with very high contrast and ultra wide viewing angle.
We've released two e-ink display for Arduino, the Grove - Triple Color E-Ink Display 2.13'' and the Grove - Triple Color E-Ink Display1.54'', today we bring you the 2.13'' Triple-Color E-Ink Display for Raspberry Pi and the 2.7'' Triple-Color E-Ink Display for Raspberry Pi. Actually, they can work as a pi hat, you just need to plug those displays into your Raspberry pi via the Raspberry pi GPIO header. The E-Ink communicates with the Raspberry pi with the 4-wire SPI interface.
At the same time, we have reserved a Grove I2C interface for using other I2C modules with this screen and a Grove digital interface which breakout two digital pin. We have added a voltage conversion module to the screen so that you can use both 3.3v and 5v modules. And with the two user buttons, you can switch between different images easily.
