Add a versatile grayscale eInk display to your Feather project with this 2.9" FeatherWing. The 296×128 pixel panel supports four levels of grey — white, light grey, dark grey, and black — giving you more visual depth than a standard monochrome display while refreshing in about one second, far faster than tri-colour eInk panels.

The FeatherWing is tested to work with all Adafruit Feather boards, from the ESP8266 to the M0 and beyond. An onboard SRAM chip handles frame buffering so even memory-constrained microcontrollers can drive the display without sacrificing precious RAM. A MicroSD socket provides storage for images and text files, and three optional buttons are available for navigation when your Feather has spare pins.
