PaPiRus Zero is an ePaper / eInk screen pHAT designed for the Raspberry Pi Zero and the new Raspberry Pi Zero W. It's one of the first truly low power displays for the Pi Zero minicomputer.
ePaper is a display technology that mimics the appearance of ink on paper. Unlike conventional displays, ePaper reflects light just like ordinary paper and is capable of holding text and images indefinitely, even without electricity. Because of this, ePaper displays and single board computers or microcontrollers are a match made in heaven as together they use a very small amount of power whilst still bringing a display to your project.
The ePaper display that comes as standard with PaPiRus Zero is a 2" (5 cm) diagonal and 200 × 96 resolution ePaper display.
One fantastic aspect of the ePaper display is the fact they don't need any power to keep the image on the screen.

The software is open source and available on GitHub.
