The PaPiRus Zero is an amazing ePaper/eInk screen pHAT crafted specifically for the Raspberry Pi Zero. It's among the first super - low - power displays for this mini computer. ePaper/eInk technology makes the screen look just like ink on normal paper. It reflects light like ordinary paper and can hold text and images without power. This means that when paired with single - board computers or microcontrollers, it uses very little power while adding a display to your project. The PaPiRus Zero comes with a 2 - inch diagonal ePaper display with a 200 x 96 resolution. Like a Kindle, you can read the screen in daylight without reflections, and it doesn't need power to keep the image. You can find wiring diagrams, datasheets, and example code at rePaper. Possible uses include making an eInk/ePaper name tag, showing the latest weather forecast, creating a Pi Zero ePaper watch, displaying your Twitter feed, using it as small dynamic digital signage, outdoor displays unaffected by sunlight, and data - logging applications. It works with any 40 - pin Raspberry Pi variant. Note that the PaPiRus Zero doesn't come with a stacking header for the Pi Zero, but you can get one separately.
Using the PaPiRus Zero is easy. First, connect it to your 40 - pin Raspberry Pi Zero or other compatible 40 - pin Raspberry Pi variant. You can find all the wiring details and example code at rePaper. Once connected, you can start using it for various purposes like creating a name tag, showing weather forecasts, or a Twitter feed. Remember, the PaPiRus Zero doesn't come with a stacking header for the Pi Zero. If you need one, you can buy it separately. As for maintenance, since ePaper displays don't require power to hold an image, there's not much you need to do. Just keep it clean and avoid exposing it to extreme temperatures or direct sunlight for long periods. If you're using it outdoors, make sure it's in a location where sunlight won't cause reflections on the screen.
