Hi everyone! I'm trying to build a weather & notification station using e Ink. However, after searching on adafruit and sparkfun I could only find extremely small displays that were extremely expensive. The largest available display from anywhere was 4.3".
Why is it so hard to find large e Ink displays and why are they so expensive? There are a ton of cool applications I want to try but can't because I can't find the hardware 
You could try hacking an Amazon Kindle or one of it's competitors. No idea what they're using to control them.
These aren't e-ink, but would any of them do?

Those displays look great! Unfortunately, they wouldn't fit into my low-power application.
The closest example would be in this youtube video: https://www.youtube.com/watch?v=pryzzH_i0os . When the display was released it was $150 and you can't even buy it right now
Take a look at this store:

They now even have the adapter board available separately again.
I have experience with several of their e-paper displays, but my post is outdated:

A good e-paper to start with, but a bit expensive, is the Waveshare 4.3:

Aliexpress and Alibaba has been hit or miss for me. Has anyone been able to order from them successfully outside of the 4.3"?
I successfully use this 7.5" SPI e-paper display:
The bigger e-paper displays have parallel interface instead of SPI. So you need an expensive development kit to start with. An I have not found a suitable adapter for the flat cable connection so far.

Hi, i was looking for a eink display with a reasonable size/price ratio for a while now and this seems to be a good choice, maybe not as good as the kindle display which you can get below $20(unfortunately it is to much hassle to actually make it usable...).
How hard is it to connect this 7,5" screen to arduino or rpi?
Can it be pluged directly without any external boards?
Are there any code examples/libraries to draw on the screen?
Does the screen allow partial update?
Any hints that would be useful?
Those questions may be silly but if i order it and than find out that it's to much for me to tackle... it would be pointless...

Hi
It could be connected using the DESTM32-S2 connection board, but the signals are 3.3V.
It could be connected without DESTM32-S2, but needs specific additional voltage supplies then.
No partial update with this display.
Bitmaps can be drawn directly, but text or graphics need ~20k bytes RAM buffer, e.g. Due or ESP8266.
All your questions are reasonable; e-paper displays are harder to use than TFTs.
There are some e-paper displays for Arduino, e.g. Waveshare 4.3 and some rare others.

Ok, thank you. I think i'll try it 
To bad that it does not support partial updates and the resolution could be a little higher but as this will be my first attempt with eink displays it should sufficient.
6" display is bare minimum for my needs. 10" or even 12"+ would be perfect but... either the price is tragic or it's to complex for me to set it up...
I just discovered that Waveshare has more e-paper displays on offer. No shield for Wemos D1 mini (yet), but an alternative to the DESTM32-S2 from Good Display, and the e-paper display itself is from? obvious if you look at the offers:

I just tried a 2.9" e-ink display - I want to use them with Pro Mini or Uno boards, but gave it up as a bad job. Has anyone used any e-ink displays with these boards, and which libraries did you use?
