Description

Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it breeze to add a tri-color display. Chances are you have 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!

We've liked these displays for long time, but breakouts were never designed for makers to use. Finally, we decided to make our own!

This breakout has a 2.7 ″ tri-color (red, black, and white) display. It has 264 × 176 black and red ink pixels and a white-ish background. Using the 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, 264 x 176 pixels x 2 colors = 11.5 KBytes. Which won't fit into many microcontroller memories. Heck, even if you have 32KB of RAM, why waste 12KB?

So we did a favor and tossed a small SRAM chip on the back. This chip shares the SPI port the eInk display uses, so you only need one extra pin. And, no more frame-buffering! You can use the SRAM to set up whatever you want to display, then shuffle data from SRAM to eInk when you're ready. The library we wrote does all the work for you, you can just interface with it as if it were an Adafruit_GFX compatible display.

For ultra-low power usages, the onboard 3.3V regulator has the Enable pin set out so you can shut down the power to the SRAM, MicroSD and display.

We even polled on a MicroSD socket so you can store images, text files, whatever you like to display. Everything is 3 or 5V logic safe so you can use it with any and all microcontrollers.

Comes assembled and tested, with some header. You'll need to solder iron to the header for breadboarding or installing into your project.
