WARNING: WE ARE NOT RESPONSIBLE IF YOU CRASH YOUR DRONE, OR FRY YOUR NANOSTATION, ETC
So here's the basic engineering:
1. Make a wiring Harness
Place two(2) 9volt batteries in series, are enough to power the nanostation for about 15-20 minutes (typical phantom vision flight time). When it starts to undervolt, the nanostation circuitry must have some good failsafe design, as it just starts blinking on/off.
Made a simple wiring harness with the two 9v battery clips, solder, and heat shrink (recommend using a spare patch cable rather than standard solid core cat5e cable (because typical patch cables are made with stranded cables rather than solid core).
FYI, Blue/Blue-White is Positive and Brown/Brown-White is negative. If you'd like, you can terminate the Orange/Orange-white and Greean/Green-White in the standard locations of an RJ45 (EIA-568-B) to allow you to plug your laptop into the nano station.
Really this is completely unnecessary as you should config the nanostation on a better power source as once you start using the 9volt batteries, you only have about 15-20 minutes of battery life. I will also mention that at the end of the battery life/flight (depending on the batteries you use) the radios start loosing power, and your db's will start to go up and over about a minute or two until it shuts off completely.
2. Remove the board out of the nanostation:
There is one screw on the back of the nanostation behind the label that allows the circuit board to simply slide out the bottom of the plastic case. Then two screws to remove the bottom plastic piece. As shown in the picture, I just hot glued two pieces of cat5 cable to the back of the board to use to attach to the drone. I am actually designing a bracket that will allow the nanostation board to attach easily to the drone (one of my school sites has 3D printer they will let me use : ) I will publish the bracket file once I complete and test the design... maybe I'll sell em somewhere too : ) as shown in the picture, I just drape the cat5 cable over the top and tape with electrical tape to secure (make sure you have about 1/4" prop clearance).
3. Fasten/tape the batteries, and wiring harness to the drone (self explanatory).
