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

Easy e-paper finally comes to microcontrollers with this breakout designed for adding a tri-color eInk display effortlessly. Leveraging technologies used in popular e-readers, the display offers a high contrast and daylight-readable screen that maintains images even when powered off.

The 2.9" tri-color screen features 296x128 black and red ink pixels on a white background. Seamlessly integrate with our CircuitPython or Arduino libraries to create and display customized frame buffers with minimal memory impact, thanks to an integrated SRAM chip. This efficient system eliminates the need for extensive RAM by directly using a shared SPI port.

Onboard power management allows ultra-low power usage, with a 3.3V regulator enabling shutdown of SRAM, MicroSD, and display power. The MicroSD socket offers additional storage for images and text files, enhancing display versatility. Supporting both 3 and 5V logic, it pairs easily with any microcontroller. The 18-pin "EYESPI" standard FPC connector streamlines GPIO connections, making solder-free assembly possible with an 18-pin 0.5mm pitch FPC cable.

Assembled and tested, the breakout comes with header needing attachment for breadboarding or project inclusion. Some examples of usage include creating dynamic information displays, low-power signage, or innovative electronic paper projects.
