Adafruit 2.9" Grayscale eInk / ePaper Display FeatherWing - SSD1680

Easy e-paper comes to your Feather with this breakout designed to add a monochrome eInk display. Featuring a 2.9" grayscale display with 296x128 pixels and an updated SSD1680 chipset, this FeatherWing supports 4 levels of grayscale (white, light gray, dark gray, black) with fast refresh times compared to tri-color displays.

This display retains the image even when power is disconnected, providing high contrast and daylight readability similar to printed paper. It is compatible with all Adafruit Feather boards from ESP8266 to M0.

Key features include built-in memory buffering and a small SRAM chip on the back to avoid large frame buffer requirements from your microcontroller. It uses SPI for communication and also includes a MicroSD card socket for storing images and text files.

• 2.9" grayscale eInk / ePaper display with 296x128 pixels
• Uses updated SSD1680 chipset supporting 4 grayscale levels
• Fast refresh: ~1 second for monochrome, ~3 seconds for grayscale
• Built-in SRAM chip for memory buffering using SPI
• MicroSD card socket for expanded storage
• Compatible with all Adafruit Feather boards including ESP8266 and M0
