Adafruit Feather Header Kit includes one 12-pin header and one 16-pin female header. These headers are more compact than the stacking headers. The headers in this kit can be soldered on either side of the Feather Board. This enables designers to plug FeatherWings into Feather Boards to add more capability in a portable project.
