Stratux Dual-Band Case w/ AHRS/GPS

thingiverse

Neatly holds all of the components needed for your dual-band Stratux ADS-B receiver. Single band case is here! Instructions Parts === Source all of the components needed for your Stratux! See the how-to reddit threads, Pt 1, Pt 2 and stay up-to-date with the Stratux subreddit. This build also requires: Two approximately 6" USB A male to USB A female extensions. I used these, but others should work fine. Minimum of four M3 x 1/4" screws to mount the GPS/AHRS chip and the Raspberry Pi. One ~6" USB A male to micro USB male (like an android charger cable) (Optional - GPS/AHRS will soon work solely through GPIO, if desired) Prints == Print one of each stl file. Dimensions (assembled) are 7.625" x 3.75" x 1.5" Two shells are recommended. Infill around 15% should be good. NYLON IS RECOMMENDED SO AS THE HEAT FROM THE COMPONENTS DOESN'T MELT YOUR BEAUTIFUL CASE Assembly == Slap it all together! First, snap the antennas into place. One of the back two antenna base grips may snap or flex. That's ok just go gentle. Both antennas should be firmly against the floor, with the wire towards the HDMI cutout side of the case (they will line up with the notch in the front antenna base grip. Route the antenna cables as you see best fit. I wrapped the ethernet-side one as you would a speaker cord, and the other is coiled underneath the Pi. Leave a few inches of the free end of the wire so you can attach it to the SRD dongles. Next, screw down the Pi. HDMI, TRRS, and Micro USB should fit nicely through their respective openings in the lower case. Use at least two M3 x 1/4" screws. Attach the SDR dongles to their USB extensions. Plug the extensions into the Pi. Then, (carefully!) rotate the SDR dongles into their cradles. Attach the antennas (doesn't matter which goes to which). If being used, prepare the GPS/AHRS as instructed in the Stratux subreddit. I prepared a "cord" by gluing several jumpers together on the Pi side connection to ease connection/separation. Carefully attach the Micro USB (~6") to the GPS/AHRS. The connector on the board is fragile, so take care to not strain the cord. Screw the GPS/AHRS into the upper portion using at least 2 M3 x 1/4" screws, orienting as shown. Carefully snap the micro USB cord into the clip on the upper portion. This may require some sanding depending on the thickness of your USB cord. To assemble the halves, carefully place the antennas (upright) into the appropriate openings in the upper half. Slide upper to lower carefully, as not to move the antennas. Connect the GPS/AHRS using the GPIO pins and/or the micro USB cable to the Pi. Carefully snap the halves together. Apply power and enjoy!
