Solder Headers onto Adafruit Feather HUZZAH
First, we'll need to solder on plain male headers onto the pins of the Adafruit Feather HUZZAH. You can follow the detailed instructions on the Adafruit Feather HUZZAH guide.
With the male headers now soldered to the Adafruit Feather HUZZAH, we can mount it to the back of 2.4" TFT FeatherWing. Line up the pins with the header and press them together until they're fully seated.
If you'd like the Weather Station to be portable, you can connect a battery. Here, we have a 2000mAh lithium ion battery. Plug in the male JST connector to the female JST port on the Adafruit Feather HUZZAH.
The enclosure cover has four standoffs that match up with the mounting holes on the 2.4" display. Orient the display and the cover so the side with black strip lines up with the opening in the lip.
If you added a battery, place it in the enclosure. Notice the two openings in the enclosure. They're for the microUSB port and the microSD card. Orient the Adafruit Feather HUZZAH so the ports line up with the openings on enclosure. Lay the cover over the enclosure and press the two together. The case has two little nubs on the edge that will click into the dimples on the lip of the cover.
And thats it! You can mount the case in all sorts of ways. For example, you can attach a magnet to the back to stick it on metal surfaces such as your refridgerator.
