Here is a new FPV goggles from Eachine. After the VR-007, the EV800 and the goggles one, with theEachine VR-D2, we have a relatively cheap goggles but offering diversity system, a 5″ 800×480 screen, -95dBm and a builtin DVR to record your FPV flights !!!. Let’s discover this bundle.
+ 1 x Eachine VR-D2
+ 1 x 2200mah 2S LiPo with DC connector
+ 1 x Charger
+ 1 x 5.8G Cloverleaf antenna
+ 1 x 5.8G Patch antenna
+ 1 x Fresnel lens clearning kit
+ 1 x Instruction manual (English)
A classic rounded goggles chassis. with 8 buttons and one Digit display located rear. It’s good to see that they directly provide a CloverLeaf antenna for short range FPV and a plannar one for long distances instead of basic twin linear models
The two top upper bottons select the Vband (5 in total are supported including the race band) and the current Vfreq Inside the current select band.
Notice the FR button plays with the right LED digit while the CH with the left one. Their respective position are clearly inverted….
The two antenna plugs are in RP-SMA format. The 6 other buttons are dedicaced for the DVR (for the first left three) and the power-saving, display settings and AV inputs selection respectively.
Good news the distance of the Fresnel lens can be ajusted via the two latteral sliders. You can ajust the focus to your current Myopia level. Unfortunatly for my personnal case, even set to the maximal distance, it’s still a little bit blurred, probably linked with my new-old eyes. The big open question: Can we use the VR-D2 while wearing correcting glasses ? The answer is yes for relatively compact ones. It’s a good news.
The headstrap have 3 anchoir points and will allow to carry the LiPo too.
The facial foam is confortable but maybe ultra large noze could meet some problems (Personally I didn’t encounter some problem while having a relatively large noze)
Installed on top the microSD card for the builtin DVR. First bad news, not all microSD card be installed. Some really basic model are not compatible and a “card full” error message will be displayed. No problem with any class 10 formatted in FAT32.
You have also two small red lights indicating the diversity activity associated with the two antenna.
No other inpout/output ports … so no AVin or AVout for example….
Close to 500g in total weight. Luckely, part the weight is equilibrated because the LiPo is installed behind the head.
The LiPo offers only a DC plug without balancer plug. So no real possibility to recharge/balance it :(… It’s a drawback versus time.
Two video inputs can be selected via the left buttons:: The direct FPV AV1 to fly FPV.
“Whitesnow” is here so synonym of a FPV friendly firmware for the display…. In practice, in flight, when the signal dissipears beyond 1s, a black screen can be here 🙁 … No indication except the AV1 logo on the top right. This logo can flickering to red … I am not sure if it’s linked with the battery level status… but for sure there is no specific battery indication status… It’s definitively a drawback…. well this bad news can be minored by the excellent autonomy of the goggles. More than 3h contineously while recording… Not bad :). More a buzzer is here to ring the bell when the lower voltage is here !!! The screen display “LO”.. With the AV1, the latency observed is low and absoluptly not a problem to practice FPV racing. Bad news, for PAL sources, few lines are cropped bottom… nothing catastrophic just 5-10 lines maximum.
The second input (AV2) is the DVR one where some OSD informations can be overlayed.
In this mode, if you long press on the “stop” button, you will enter into the DVR menu settings … and here you will recognize the HMDVR/Eachine Pro DVR OS… So no real doubt about the builtin DVR
By default, the VGA resolution is selected recording in 640×480 @25fps
Good news you can select and save the D1 mode but resolution goes to 720×480, a NTSC D1 format@25fps …
For PAL source recording, the close too 756-480=76 bottom lines are not recorded loosing for example some important OSD informations. It’s a known problem for the HMDVR/pro DVR modules. 🙁
At least for pure NTSC sources, recordings are pretty good and the RX sensitivity is very good better than my Boscam GS922 for example (announced to be “only” -90dBm)
Video time must be set to off if you want to record more than the default 10min flight session. I was able to record without problem a 1h20min file.
EDIT 09/29/16. A new PAL firmware firmware is now available to solve the PAL recordings cropping. Remains the AV1 few bottom lines cropped and blackscree
What is a little bit annoying, you will have to first go from AV1 to AV2 to start recording, then return in AV1 to enjoy low latency display then return to AV2 to stop and/or playback the file.
The main PCB of the FPV screen
On the other side, the DVR board… very similar to the Eachine ProDVR
Good news, a Buzzer is here to ring the low voltage alarm
UNBOXING & ANALYSIS
A good product with a good non-HD screen and good facial adaptation/. For just few bucks more than ancestor goggles models, you have some adapted FPV racing antennas, a builtin DVR recording superbly NTSC sources and with a great RX sensitivity. I regret mainly the presence of the PAL bug cropping mainly bottom part of FPV recordings for PAL sources. The time to time presence of a black screen in lost signal conditions is also problematic. A good step forward from Eachine but not yet the perfect product.
+ Diversity system
+ Cloverleaf/planner antennas
+ Builtin DVR
+ 5″ screen
+ 3h of autonomy
+ Ajustable distance lens
+ Great RX senstivity
+ Compact eyeglasses can be used with

– Black screen when signal is lost more than 1s (diversity problem)
– Individual -90dBm receiver (not -95dBm)
– No AVin/AVout ports
– Not compatible with all microSD card
– Poor patch antenna performances
– Light leak close to the noze section
