A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing OLED: it adds a 128×32 monochrome OLED plus 3 user buttons to any Feather main board. Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top of your Feather board and let the board take flight!

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 128×32 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 toss on a reset button and three mini tactile buttons called A B and C so you can add a mini user interface to your feather.

Please note that OLED displays are made of hundreds of…OLEDs! That means each pixel is a little organic LED, and if its kept on for over 1000 hours it’ll start to dim. If you want to keep the display uniformly bright, please turn off the display (set the pixels off) when it isn’t needed to keep them from dimming.

Tested working with all Feather boards. The OLED uses only the two I2C pins on the Feather, and you can pretty much stack it with any other FeatherWing, even ones that use I2C since that is a shared bus. To use, Check out our tutorial ! It has schematics, datasheets, files, and code examples.
