Adafruit FeatherWing 128x32 OLED Add-On for Feather

Adafruit FeatherWing 128x32 OLED Add-On for Feather adds a 128x32 monochrome OLED plus three user buttons to any Feather main board. The board comes fully assembled with no soldering required. The display is only about 1" diagonal but is very readable due to high contrast. The screen is made of 128x32 individual white OLED pixels. It makes it's light, so no backlight is required. This feature reduces the power necessary to run the OLED and is why the display has such high contrast.
