Review: PaPiRus ePaper Screen HAT for Raspberry Pi

The objective of the PaPiRus ePaper Screen HAT for Raspberry Pi is to make ePaper technology available to anyone, which is why it is a fully open source product with schematics and source code at GitHub. Besides the ePaper display, the HAT also has four pushbuttons, a real-time clock (RTC) and a temperature sensor.
