Adafruit 1.54" Monochrome eInk / ePaper Display with SRAM - 200x200 with SSD1681 and EYESPI

Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add an 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 sports a 1.54" monochrome (black and white) display with 200x200 black pixels on a white-ish background. It has a higher resolution and faster update time than the 1.54" tri-color display (only a couple of seconds update time instead of 15 seconds).

Using CircuitPython or Arduino libraries, you can easily create a 'frame buffer' with pixel data to output to the display. The breakout includes a small SRAM chip that shares the SPI port used by the eInk display to offload your microcontroller memory. This allows more efficient display updates by storing image data in SRAM and only sending it to the eInk when ready via a dedicated library.

Features include an onboard 3.3V regulator with Enable pin to shut down power for ultra-low power use, a microSD socket for storing images or text, and full 3V/5V logic compatibility for use with various microcontrollers.

The display breakout comes assembled and tested with some header; soldering is required to attach headers for breadboarding or project installation. An 18-pin "EYESPI" standard FPC connector is included for easy cabling with a compatible 0.5mm pitch FPC cable.
