Adding an e-ink display to the Raspberry Pi


Introduction

Most people know e-ink or e-paper displays from reading devices like the „Amazon Kindle“.

For a few months there are e-paper displays available that can be directly accessed by an Arduino or a Raspberry Pi.

One popular e-paper display kit is the „Repaper display kit“, that is available with displays in different sizes (between 1.44” and 2.7”).
More information can be found here: http://repaper.org/reference.html

I bought the 2.7″ version. Here is what is included in the kit:

Demo

So if you have everything wired correctly and loaded and installed all the drivers, you can run some demos:

And you also can try, what will happen to the display, when you remove the power supply – the display information will be retained 🙂
