Display Wings let you add a monochrome or color display for lots of data. These are very popular, as you can imagine, for adding a user interface.
These Wings work with all Feathers.
You can only really use one display at a time. The OLED Featherwing uses only I2C and works with any other Wings. The TFT 'wing uses a lot of pins, so works best with only I2C Wings.
This tiny Wing is so cute, and it has a 128x32 monochrome OLED display. OLEDs have a crisp and high-contrast look, so they are great for indoor and some outdoor use. There's no backlight so they use little power (only as much as the pixels that are lit).
The OLED is connected over I2C so it uses only two pins. In addition, there are 3 little buttons connected directly to three GPIO pins. You can use the buttons to add basic interactivity. Only one OLED FeatherWing can be used with a Feather board.
This feather has a 0.96" 160x80 Color TFT Display with 16-bit full color capability. And, so you can make a proper UI, it has a 5-way navigation switch and two push buttons. The joystick can go left, right, up, down and 'in' for selection. Two buttons on the side can change modes or whatever you like.
If you need a bigger and more colorful screen, the TFT FeatherWing has just about everything. There is a 320x240 full-color TFT display. There is also a resistive touchscreen on top, for interactivity. On the bottom is a microSD card holder so you can store images or data to be displayed. We also toss in an on-off switch.
The display is much bigger than the OLED, and uses the SPI port for communication with the TFT/touch/SD card.
The Wing requires an additional two pins for the TFT. One additional pin if you are using the touch screen, and one extra pin if using SD interface. (So, SPI + 4 GPIO pins max if using all three)
Unlike other wings, this one is fully assembled and the feather plugs into the bottom. If you want to stack Wings, you'll need to solder stacking headers to the Feather, then stack on top of that.
Spice up your Feather project with a beautiful 3.5" touchscreen display shield with built in microSD card socket. This TFT display is 3.5" diagonal with a bright 6 white-LED backlight. You get a massive 480x320 pixels with individual 16-bit color pixel control. It has way more resolution than a black and white 128x64 display, and twice as much as our 2.4" TFT FeatherWing. As a bonus, this display comes with a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen
This FeatherWing uses a SPI display, touchscreen and SD card socket. It works with any and all Feathers but given the large display it works best with our faster boards like the nRF52, ESP8266, ESP32, M0, M4, WICED, and Teensy. We also include an SPI resistive touchscreen controller so you only need one additional pin to add a high quality touchscreen controller. One more pin is used for an optional SD card that can be used for storing images for display.
This Wing comes fully assembled with dual sockets for your Feather to plug into. You get two sockets per pin so you can plug in wires if you want to connect to Feather pins. Alternatively, each pin has a large square pad on the PCB for direct soldering.
