Guided Tour

Let’s have a quick look at the FeatherWing and what’s on it.

Guiuded Tour

  • 2.6” 320x240 16-bit color LCD with resistive touch screen - The LCD driver (ILI9341) is interfaced over SPI, the touch driver (TSC2004) is interfaced over I2C.
  • QWERTY keyboard - A BB Q10 keyboard connected to a SAMD20, the key FIFO can be easily accessed over I2C.
  • 5-way button - Great for navigating menus, also connected to the SAMD.
  • 4 soft tactile buttons - Feel very nice to press, use them for whatever function you want; also connected to the SAMD.
  • Neopixel - Allows you to show the status of your board.
  • Ambient Light Sensor - Connected to Analog pin 5, can be used to dim the backlight based on the ambient light levels.
  • microSD connector - Gotta keep those photos and other files somewhere, am I right?
  • Stemma QT/Qwiic connector - Opens the door to an ecosystem of dozens, if not hundreds, of Stemma QT/Qwiic boards.
  • On/Off switch - Connected to the Feather Enable pin, turns off the Feather at LDO level (varies between Feathers), as well as 5V
  • GPIO expander - The SAMD20 also doubles as a I2C GPIO expander, you can access the Touch INT, and Card Detect over the expander, also there are a few test points for extra GPIOs.
  • Dual row sockets - Thanks to these, you can still access the Feather pins even when the Feather is plugged in!
  • Four mounting holes - Use these for enclosures or to attach a lanyard.
  • GPIO solder jumpers - Almost all GPIOs can be disconnected from the FeatherWing, just in case you have something else in mind for them.
