My Feather doesn't have male pins. How do I plug it into the EmotiBit?

The Adafruit Feather M0 WiFi can come with a stacking header. This has male pins on the bottom and female sockets on the top allowing you to easily access the Feather pins and add additional FeatherWings even when plugged into an EmotiBit.

When your Adafruit Feather arrives, it likely has the male pins inserted into anti-static foam. You can remove the foam to find the male pins and stack the EmotiBit + Feather.
