DESCRIPTION

Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-colour 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 2.13" tri-colour (red, black, and white) display. It has 250x122 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, 250 x 122 pixels x 2 colours = 7.5 KBytes. Which won't fit into many microcontroller memories. Heck, even if you do have 32KB of RAM, why waste 8KB?

A small SRAM chip has been added to 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.

For ultra-low power usages, the onboard 3.3V regulator has the Enable pin brought out so you can shut down the power to the SRAM, MicroSD, and display. Everything is 3 or 5V logic safe so you can use it with any and all microcontrollers. Finally, a MicroSD socket has also been included so you can store images, text files, and whatever you like to display.
