Adafruit 3.52" 340x180 Quad-Color eInk / ePaper - Bare Display

by Adafruit

What's better than a tri-color E-Paper display? Quad-color, of course! This is a 3.52" 340x180 Quad-Color eInk / ePaper Bare Display. 

E-Ink/E-Paper displays make for great low-power displays that are daylight visible and keep their image even when depowered.

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!

Please note: this is the bare display element plus an adapter cable. You need to plug it into a board with a 'standard' 24-pin FPC e-paper connector. We recommend checking out and picking up a matching driver board:

  • Feather RP2040 ThinkInk - solderless plug-and-play solution with Arduino or CircuitPython support. Definitely the easiest way to get started, and is what we show in the demo above
  • eInk Feather Friend - FeatherWing add-on for any Feather board)
  • eInk Breakout Friend - breadboard-friendly adapter that gives you level-shifting and components for quick eInk connectivity.

This is a 3.52" quad-color (red, black, yellow, and white) display. It has 340x180 black, red and yellow ink pixels and a white-ish background. It uses the JD79667 chipset, so make sure whatever firmware code you are planning to use has support for it. The Arduino library we wrote does all the work for you, you can just interface with it as if it were an Adafruit_GFX compatible display.

Unlike the vast majority of e-Ink displays, this one has a 'flipped' connector, with bottom contacts instead of top. You can use it with standard 24-pin E-Ink driver boards, but you need to attach the included extender and Flex A-B cable, which will flip the contacts over and make it work as expected.

Note that you cannot overlay/mix pixels: each point can be one of the four colors, but you can't, like, mix the red and yellow to make an orange. Instead, check out our guide on dithering!
