Adafruit 2.9" Red/Black/White eInk Display Breakout is a 2.9" tri-color (red, black, and white) display. It has 296x128 black and red ink pixels and a white-ish background. Using the Adafruit CircuitPython or Arduino libraries, the user can create a 'frame buffer' with what pixels they want to have activated and then write that out to the display. The display breakout includes a small SRAM chip on the back. This chip shares the SPI port the eInk display uses, so the user only needs one extra pin. The SRAM can be set up whatever the use wants to display, then shuffle data from SRAM to eInk when ready. For ultra-low power usages, the onboard 3.3V regulator has the Enable pin brought out so the power to the SRAM, MicroSD, and display can be shutdown. There is also a MicroSD socket so the user can store images, text files, or whatever the user wants to display. Everything is 3 or 5V logic safe so it can used with any and all microcontrollers. Comes assembled and tested, with some header. A soldering iron will be needed to attach the header for breadboarding or installing it into a project.
