Fatshark Attitude V2 Nexwave raceband receiver module upgrade

Upgrading to a Nexwave raceband receiver in Fatshark Attitude V2

parts

I’m very happy with my Fatshark Attitude V2 goggles. They are small, not as bulky as the single screen goggles such as The Quanum FPV goggles or the Eachine VR 007 goggles. Although when buying the Attitude V2s I quickly realized that the default fatshark channels wasn’t enough for me. I wanted to be able to use both the Boscam band and raceband. I have a seperate Boscam rc305 receiver that I use together with a 7″ monitor for some applications. I didn’t want to constantly change transmitter band/channel depending on if I wanted to use my monitor or Fatsharks so I decided to change the stock receiver module in my Fatshark Attitude V2 to the Fatshark Dominator Reciever 5.8GHz 32 Channels RX Module RaceBand

Installing it into the Fatshark goggles

Step 1 – Open the goggles

The first step is to open up the goggles case. You need to remove the rubber eye cups, some screws and the image settings adjustment knob on top of the goggles. You must be very careful when seperating the two halves so that no cables are caught and ripped of their sockets or soldering pads.
There is a youtube video explaining this process here:

Step 2 – Remove the old receiver module

In this step you need to remove the whole PCB containing the receiver module from the Fatshark goggles. There is two cables that you need to unplug and then you can just pull it out.

Step 3 – Solder the new Nexwave module to the receiver board/PCB

Soldering module
I contacted the Fatshark technical support and ordered a new “Attitude V2 receiver replacement board” through them. This way I didn’t have to desolder the old receiver module from the PCB and if I ever need to I can quickly insert the old module. The replacement board costs around 30$ and is well worth it.
Soldering the new Newwave receiver module to the board is an easy task, just make sure thate the module is flush to the pcb before soldering. I fixed mine with some electrical tape and it ended up flush with the board.

Step 4 – Drill a hole for the band change DIP-switches

To be able to change which band the receiver should operate on you need to be able to access the small DIP-switches below the antenna plug or it defeates the purpose of this mod. The easiest way is to CAREFULLY drill a hole in the fatshark goggles and change the switches with a needle. Use a caliper to measure where the hole need to be. I used a 6mm drill.

Step 5 – Insert the new receiver module and check hole alignment

receiver module dry fit
Plug in the cables to the receiver board again and gently push the board into place in the goggles. It’s a snug fit but not much pressure is needed, make sure that no cables are in the way.
When the module is is place you can actually test your goggles to make sure that everything is working. Double check that the cables are plugged in the wrong way and that no loose screws are shorting anything before plugging in the battery.

Tada! now you should be able to match the frequency with your transmitter and get a solid video feed.

Step 6 – Assemble the goggles

Carefully put everything back together and you’re done.
I 3d-printed a faceplate and attached it to the goggles for a more comfortable fit, I will soon post a guide on that mod.
