Adafruit 1.54" 3 Color ePaper Display with SRAM, Red Blk Wht 3625

Easy e-paper finally comes to microcontrollers with this breakout that is designed to make it easy to add a tri-color eInk display. Chances are you've seen e-readers like the Kindle or Nook. They have gigantic electronic paper "static" displays which means the image stays on the display even when the power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper.

This small 1.54" tri-color display has 152x152 black and red ink pixels and a white background. Using Adafruit's Arduino library, you can create a "frame buffer" with the pixels you want to have activated and then write it out to the display. There is a small SRAM chip on the back. This chip shares the SPI port the eInk display uses so you only need one extra pin.

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 Adafruit 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 usage the onboard 3.3V regulator has the Enable pin brought out so you can shut down the power to the SRAM, MicroSD and display. There is even 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. It comes assembled and tested and includes a header. You will need a soldering iron to attach the header for breadboarding or installing into your project.
