Woah, the cyber-future is here! Flexible E-Ink has been demo'd at high tech events for years but now you can actually get your paws on it. This display is true E-Ink / E-Paper, once an image is displayed it will stay even once you remove all power. The image is also high contrast and very daylight readable. It really does look just like printed paper!
This flexible display sports a 2.9" monochrome (black and white) display. It has 296x128 black ink pixels on a white-ish background. The monochrome displays also take a lot less time to update, only a couple seconds instead of 15 seconds.
Please note: this display is flexible but that doesn't mean you can constantly flex it.
Using our CircuitPython or Arduino libraries, you can create a 'frame buffer' with what pixels you want to have activated and then write that out to the display. Most simple breakouts leave it at that. But if you do the math, 296 x 128 pixels = 4.7 KBytes. Which won't fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 5KB?
Note: This is just the display. You'll want your own eInk Breakout Friend too!
