Feathers

Feathers are the main/mother boards of the Feather platform.

You always need one Feather and can add zero or more FeatherWings to increase the capabilites.

For example:

  • Feather Huzzah ESP8266 + Music Maker FeatherWing = MP3 streaming player
  • Feather 32u4 Bluefruit + NeoPixel FeatherWing = Bluetooth LE controllable RGB lamp
  • Feather 32u4 FONA + GPS FeatherWing = Cellular GPS locator with SMS control
  • Feather nRF52 Bluefruit + Motor FeatherWing + Robot Chassis = Phone-controlled robot rover
  • etc!

All Feathers...

  • All Feathers have a microcontroller that can be programmed by Arduino IDE
  • All Feathers are 3.3V logic
  • All Feathers come with a MicroUSB connector that is used for data and power
  • All Feathers have a bootloader, and do not require a separate programmer device
  • All Feathers have USB Serial for debug (sometimes it is part of a native USB interface, sometimes via a USB-serial adapter chip)
  • All Feathers are 0.9" wide, and fit in a breadboard with 1 row available on one side, and two rows on opposite side.
  • Almost all are 2.0" long (M0 ATWINC Feathers and FONA Feathers are the exceptions)
  • All Feathers have the same two mounting holes near the USB port
  • All Feathers have Power, I2C, SPI, UART pins in the same location. Remaining pins try to be as similar as possible (but they may have different pin names/numbers)
  • All Feathers can run from USB or LiPo battery, and have a LiPo charger built-in

Most Feathers...

  • Most of the Feathers have a wireless module built in
  • Most of the Feathers have an Enable pin that will allow shutdown via logic level (Teensy and FONA Feathers are the exceptions)
  • Most of the Feathers have a native USB connection (nRF52 and ESP8266 are the exceptions)

No Feathers

  • No feathers are guaranteed to be 5V-input compliant. Use 3.3V logic only please!
