Pinouts

The Terminal Block Featherwing doesn't have any active components. Instead, it just breaks out all the existing connections from a Feather. Note that Feathers use different chipsets so not all pins are labeled on purpose!

The only pins you can depend on are:

  • 3.3V power
  • 3.3V enable
  • VBat power
  • USB power
  • GND
  • Reset
  • I2C: SDA & SCL
  • SPI: MOSI, MISO, SCK
  • UART: RX & TX

Check your Feather documentation and product page for details on what other pins are available and what they are connected to
