I recently purchased a lot of Ehang goggles at a local auction. I knew the quality would no where close to Fatsharks but they would probably good backseat driver spectator goggles. Here are a few specs
- Front Facing Camera
- Internal 1s 1700mah lipo
- 32 channel auto search
- USB micro charge port able to use power banks to charge and fly
- AV output port
- 2.8g antenna for head tracking data for Ghost VR drone
- 5.7g antenna (no diversity)
- 3 headstrap system for better hold and comfortable wear
The camera unfortunately has no IPD, no diversity, a decent screen, no DVR and a subpar antenna.

The camera switch button also turns off the built in reciever so there is no interference.
To install the diversity module just cut and strip the camera connector and use 1p Dupont connector to hook it up to the diversity module to the according 5v, ground and visual signal. No voltage booster needed since the camera uses 5v.
The hardest part will be fitting the module. I will take a dremel to it and see what I can do.

The dremel was a little too much noise for my 5 month old. I was able to sneak the wires out the small camera hole. So there are major differences between the IOS and Android goggles.
