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.
Connect Slide Switch (Optional)
If you'd like to turn off the circuit without having to remove the display from the case, you can break out the slide switch. You'll need to wire up a a slide switch. It will need to connect to the EN and GND labeled pins on the 2.4" TFT FeatherWing. Here, we connected the terminals of slide switch to jumper cables. The jumpers can plug into the female headers on the 2.4" display.
I used the tips from male jump cables to create a "slim" version by removing the plastic housing and trimming it short. Then, I soldered the tips to pieces of wire – This way, I can easily plug into the female header on the TFT display.
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.
