PaPiRus Zero is an ePaper / eInk screen pHAT designed for the Raspberry Pi Zero. It’s one of the first true low power displays for the Pi Zero mini computer.
Since the launch of the original PaPiRus on Kickstarter, we’ve come to realise how popular ePaper screens HATs are for hobbyists and makers. This has led to the development of PaPiRus Zero for the Pi Zero.
ePaper / eInk is a display technology that mimics the appearance of ink on normal paper. eUnlike 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.
Potential Use Cases:
An eInk / ePaper Nametag
Display the latest weather forecast
A Pi Zero ePaper watch
Display your own Twitter Feed
Small dynamic digital signage (such as displaying prices for products in a store)
Outdoor displays where you don’t want the screen to be affected by sunlight reflection
PaPiRus Zero – ePaper / eInk Screen pHAT [Discontinued]
the PaPiRus Zero pHAT is a nice display for everybody who wants to show information that doesn't change frequently. For this purpose (and if you are happy with b/w) this display is great. The resolution is not too big (200x96), but enough for a lot of purposes. The contrast is very good.
There are a few things that I would like to see improved, e.g. having a switchable backlight would be great, also the programming interface is not my preference (using a fuse-based epd daemon creating a new device), but that does not really reduce my fun with the little display.
The only bigger concern I have (this is why I rated it "only" with 4 stars) is the sharp corners of the display glass. I suspect you can easily get handling damage on the display, or even worse, cut yourself. Therefore: be careful when handling the display!
