The PaPiRus is a HAT for the Raspberry Pi that is capable of driving an ePaper display with ease by making use of the existing open source RePaper codebase and examples. ePaper / eInk 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.
All signals are broken out to a 40 pin female header. This version of the HAT works perfect with the Raspberry Pi 3 B an B+ and is equipped a 2.7" diagonal and 264 x 176 resolution true ePaper / eInk graphical display.
The display does not require any power to keep the image and will stay 'on' without any power connection for many days before slowly fading. Of course, its also daylight readable and is very high contrast. This makes it excellent for data-logging applications, outdoor displays, or any other ultra-low power usages.
