The FeatherWing Proto is a prototyping add-on board compatible with all Adafruit Feather boards. It provides duplicate breakouts for every Feather pin, a grid of proto holes for custom circuitry, and connected pad strips for GND and 3.3V — everything you need to add custom components to your Feather project.

Stack it on top or below your Feather board using stacking headers or female headers (sold separately) for a compact, portable build.

Key Features

  • Universal Feather Compatibility – Works with all Adafruit Feather boards
  • Duplicate Pin Breakouts – Every Feather pin broken out for easy access
  • Proto Grid – Plenty of through-holes for custom circuitry
  • GND & 3.3V Strips – Connected pad strips for convenient power distribution
  • Stackable – Mount above or below your Feather with stacking headers

Ideal For

  • Adding custom circuitry to Feather projects
  • Prototyping with buttons, LEDs, and sensors
  • Compact, portable project builds
  • Expanding any Feather board's capabilities

Package Contents

  • 1× FeatherWing Proto Board
Note: Headers are sold separately. Use Feather Stacking Headers for multi-wing builds or Feather Female Headers for a single add-on.

Jargon buster

Plain-language definitions for the technical terms used above.

FeatherWing
A FeatherWing is an add-on board made to plug into the Feather microcontroller board layout. Knowing a product is a FeatherWing helps you check whether it will physically and electrically fit your Feather-style mainboard.
Headers
Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
