Assembled Adafruit FeatherWing OLED - 128x32 OLED Add-on For Feather

A Feather board without ambition is a Feather board without FeatherWings! This is the Assembled FeatherWing OLED: it adds a 128x32 monochrome OLED plus 3 user buttons to any Feather main board. Comes fully assembled so you can connect a FeatherWing on top of your Feather board and let the board take flight, no soldering required!

These displays are small, only about 1" diagonal, but very readable due to the high contrast of an OLED display. This screen is made of 128x32 individual white OLED pixels and because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! We also include a reset button and three mini tactile buttons called A, B and C so you can add a mini user interface to your Feather.

Note that OLED displays are made of hundreds of organic LEDs (OLEDs)! If kept on for over 1000 hours, they will start to dim. To keep the display uniformly bright, turn off the display (set pixels off) when it's not needed.

Tested to work with Feather 32u4, M0, and ESP8266 boards. The OLED uses only the two I2C pins on the Feather and can be stacked with any other FeatherWing, even those using I2C since it's a shared bus. To use, simply follow the tutorial to install our Arduino library at https://learn.adafruit.com/monochrome-oled-breakouts. It's basically a Feather-shaped version of the 128x32 I2C OLED breakout here.
