**[City, State] -** Adafruit, a leading provider of open-source hardware and electronics, has released a new FeatherWing featuring a 2.9″ tri-color eInk display, offering makers a unique and powerful way to add e-paper capabilities to their Feather boards.

The FeatherWing boasts a 296×128 pixel display capable of displaying red, black, and white, similar to the displays found in e-readers like the Kindle or Nook. The display utilizes black and red ink pixels on a white background, achieving high contrast and exceptional daylight readability.

This new FeatherWing is designed for seamless integration with a wide range of Adafruit Feather boards, from the ESP8266 to the M0. It includes built-in memory buffering, allowing compatibility with even smaller microcontrollers like the ’32u4 and ‘328. While utilizing the standard SPI pins for communication, the FeatherWing also features up to four control pins for managing the SD card slot and SRAM. Three optional buttons are also available for Feathers with compatible pins.

To address the challenge of limited memory on some microcontrollers, Adafruit has included a small SRAM chip on the FeatherWing. This chip shares the SPI port with the eInk display, requiring just one extra pin for operation. It eliminates the need for frame-buffering, enabling users to set up their desired display content in the SRAM and then transfer it to the eInk display when ready. The included library simplifies the process, allowing users to interact with the display as if it were an Adafruit_GFX-compatible display.

For even greater flexibility, the FeatherWing includes a MicroSD socket for storing images, text files, and other content. The FeatherWing comes pre-assembled and tested, with socket headers that allow for effortless connection to any Feather board without soldering.
