Adafruit 2.9" Red/Black/White eInk Display Breakout - THINK INK - SSD1680 Chipset

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. Featuring a 2.9" tri-color (red, black, and white) display with 296x128 black and red ink pixels and a white-ish background, it offers a high contrast, daylight-readable, static electronic paper display that retains the image even when power is disconnected.

This breakout includes a small SRAM chip on the back that shares the SPI port with the eInk display, allowing use of SRAM to set up the display data before shuffling it to the eInk. This eliminates the need for large frame buffers in microcontroller memory. The display is compatible with CircuitPython and Arduino with existing libraries available.

Additional features include an onboard 3.3V regulator with an Enable pin to shut down power for ultra-low power use cases, a MicroSD socket for storing images or text files, and a standard 18-pin "EYESPI" flip-top FPC connector. Comes assembled and tested with some header (soldering required).
