A Feather board without ambition is a Feather board without FeatherWings! This is the FeatherWing OLED: it adds a 128x32 monochrome OLED plus 3 user buttons to any Feather mainboard. Using stacking headers or 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 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! Adafruit also tosses 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 it is 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. 

Features and specifications:

  • Small OLED display, 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.
  • Comes with a reset button and three mini tactile buttons called A B and C so you can add a mini user interface to your feather.
    • If you're using ATmega328P, Atmega32u4, ATSAMD51 M4, or ATSAMD21 M0 Feather
      • Button A is #9 (note this is also used for the battery voltage divider so if you want to use both make sure you disable the pullup when you analog read, then turn on the pullup for button reads)
      • Button B is #6
      • Button C is #5
    • If you're using ESP8266
      • Button A is #0
      • Button B is #16
      • Button C is #2
    • If you're using WICED/STM32 Feather
      • Button A is #PA15
      • Button B is #PC7
      • Button C is #PC5

Note: Button B has a 100K pullup on it so it will work with the ESP8266 (which does not have an internal pull-up available on that pin). You will need to set up a pullup on all other pins for the buttons to work.

  • Tested works with all of Adafruit's 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. It does all of the data transfer over the I2C pins, highlighted above SDA and SCL. No other pins are required. There are two 2.2K pullups to 3V on each. These pins can be shared with other I2C devices.

Note: The I2C address is 0x3C and CANNOT be changed
