Three colour 2.9 Inch eInk display breakout lands at Adafruit for $34.95
If your next electronics project requires an eInk display you may be interested to know that Adafruit has announced the availability of the 2.9″ Red/Black/White eInk Display Breakout, THINK INK priced at $34.95. Check out the video below to learn more about the eInk display breakout screen which measures 80.0mm x 47.0mm x 5.0mm or 3.1″ x 1.9″ x 0.2″ and weighs just 23.0g or 0.8oz.
“Easy e-paper finally comes to microcontrollers, with this breakout that’s designed to make it a breeze to add a tri-color eInk display. Chances are you’ve seen one of those new-fangled ‘e-readers’ like the Kindle or Nook. They have gigantic electronic paper ‘static’ displays – that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!”
“This breakout has a 2.9″ tri-color (red, black, and white) display. It has 296×128 black and red ink pixels and a white-ish background. 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 x 2 colors = 9.5 KBytes. Which won’t fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 10KB?”
