Adafruit FeatherWing Proto - Prototyping Add-on For All Feather Boards
A Feather board without ambition is a Feather board without FeatherWings!
This is the FeatherWing Proto - a prototyping add-on for all Feather boards. Using Stacking Headers or Female Headers you can connect a FeatherWing on the top or bottom of your Feather board and let the board take flight!
This has a duplicate breakout for each pin on a Feather, as well as a bunch of plain grid proto holes. For GND and 3.3V, there is a strip of connected pads. There's plenty of room for buttons, indicator LEDs, or anything for your portable project. The FeatherWing Proto makes an ideal partner for any Feather board.
