Adafruit 2.7" Tri-Color eInk / ePaper Display with SRAM - Red Black White

Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-color eInk display. This 2.7" tri-color (red, black, and white) display has 264x176 black and red ink pixels and a white-ish background. The display retains the image even when power is completely disconnected, providing high contrast and very daylight readable visuals, just like printed paper.

The Adafruit 2.7" Tri-Color eInk / ePaper Display includes a small SRAM chip on the back which shares the SPI port of the display, allowing you to buffer display data without using valuable microcontroller RAM. The included libraries for CircuitPython and Arduino enable easy interfacing with this display as an Adafruit_GFX compatible display. For ultra-low power usage, the onboard 3.3V regulator has the Enable pin available to shut down power to the SRAM, MicroSD, and display.

The breakout also features a MicroSD socket for storing images, text files, or other data for display. It is compatible with both 3V and 5V logic levels, making it suitable for use with a wide range of microcontrollers.

This product comes assembled and tested with some header; soldering is required to attach the header for breadboarding or project installation.
