We have been working with Pervasive Displays to bring to market a Raspberry Pi ePaper HAT module, called the PaPiRus, that is capable of driving ePaper displays of various sizes with ease,
making use of their existing open source RePaper codebase and examples. 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.
We are very excited to offer this Raspberry Pi ePaper HAT compatible display breakout for hackers who want to start playing with small ePaper / eInk displays in their Raspberry Pi projects.
PaPiRus was originally launched on Kickstarter, and is now available to purchase!
The PCB assembly has a lot of driver circuitry required to keep the display running smoothly as well as an EEPROM for HAT compatibility and easy plug and play operation with the Raspberry Pi.
All signals are broken out to a 40 pin female header. The display included in this offering is a 1.44" diagonal and 128 x 96 resolution true ePaper / eInk graphical display.
These are intended for use as small dynamic signage in grocery stores since a barcode displayed on it can be scanned by a laser barcode-reader.
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 The good news is that rePaper/PDI have provided a suite of example code for the Raspberry Pi along with datasheets.
Tons more information including wiring diagrams, datasheets & and links to example code at rePaper! Also, check out our eInk/ePaper display for the Pi Zero.
我们一直在与Pervasive Displays合作，将一种名为PaPiRus的Raspberry Pi ePaper HAT模块推向市场，该模块能够利用其现有的开源RePaper代码库和示例，轻松驱动各种尺寸的ePaper显示器。ePaper是一种模拟纸上墨水外观的显示技术。
与传统显示器不同，ePaper反射光线，就像普通纸张一样，即使没有电，也能无限期地保存文本和图像。正因为如此，ePaper显示器和单板计算机或微控制器是天作之合，因为它们在一起使用非常少的功率，同时仍然为您的项目带来显示器。
我们很高兴为那些想在Raspberry Pi项目中开始使用小型ePaper/eInk显示器的黑客提供这款Raspberry Pi-ePaper HAT兼容显示器。PaPiRus最初在Kickstarter上推出，现在可以购买！PCB组件具有保持显示器平稳运行所需的大量驱动电路，
以及用于HAT兼容性和与Raspberry Pi轻松即插即用操作的EEPROM。
所有信号均传输至一个40针的母头。此产品中包含的显示器是一个1.44英寸对角线和128 x 96分辨率的真ePaper/eInk图形显示器。这些显示器旨在用作杂货店的小型动态标牌，因为其上显示的条形码可以被激光条形码阅读器扫描。
显示器不需要任何电源来保持图像，在没有任何电源连接的情况下会“打开”好几天，然后慢慢消失。当然，它也是日光可读的，对比度很高。这使得它非常适合数据记录应用程序、户外显示器或任何其他超低功耗用途。好消息是，
rePaper/PDI为Raspberry Pi提供了一套示例代码以及数据表。更多信息，包括接线图、数据表和rePaper示例代码的链接！此外，请查看Pi Zero的eInk/ePaper显示屏。
