TEST: Eachine EV800, cheap 5″ 40CH FPV goggles, quantum V2 competitor ?

null

EDIT 07/21/16

Now the EV800 is updated with these addings/modifications

1 :26g weight reduction
2 :Added one sponge
3: Changed to be 3.5 mm headphone jack
4: Added “AV in” Interface

INTRODUCTION

The valse of cheap FPV goggles is opened since the introduction of the Hobbyking Quantum. After the first Eachine VR007,
with the Eacchine EV800 here is the new revision/evokution with at least two improved points: i) a 5″ FPV screen with 800×480 resolution and ii) a 40CH 5.8G builtin VRX. Let’s discover the bundle.

BOX CONTENT

null

+ 1 x Eachine EV800 (with a 1S 2000Ah builtin LiPo)
+ 1 x USB charger
+ 1 x 5.8G Linear antenna (RP-SMA connector)
+ 1 x 2.5mm male to 3.5mm female jack adaptor
+ 1 x Power lead cable with JST connector
+ 1 x Cleaning tissue
+ 1 x Instruction manual (English)

OVERVIEW

The EV800 is build with a high quality mate & soft plastic very pleasant to touch. The general size is increased versus the VR007, more deeper.

null

You can split in two the goggles to transform it into a small FPV monitor, a very original idea.

null

The slliding locking system

null

The fresnel lens is assumed to offer a 3x magnifying capacity, stronger than for the VR007. The Fresnel lens can be replaced of course by another model.

null

Unfortunatly, no possibility here to ajust the Lens distance … πŸ™ It would have been a great point versus the Quantum cyclops goggles for example.

-Side view

The left side welcome the main lead power connector, a small format a little bit fragile after multiple insertions IMHO

null

An extra cable can be found in the bundle. Thanks to this one, you can probably plug an external 1S LiPo with JST connector. A good point if you are running out of the internal 2000 LiPo (strong enough to offer 2h of usage)

null

The right side welcomes a audio out in 2.5mm jack format

null

An 2.5mm to 3.5mm adaptor is provided

null

-Rear view

Horror, any foam is installed !!!! A direct contact with the skin…. Not only it will be painful versus time but your skin will sweat a lot locally.

null

null

The distance between the Fresnel lens to the middle eye position on the goggles border is approximatively of 6cm. Since I am not wearing any view glasses, I can’t conclude if it’s compatible or not

null

-Upper view

The uppser side welcomes all the control buttons as well as the 5.8G RP-SMA connector and the battery charge led status. From left to right: the scanning search, the RP-SMA connector, the battery charge status, the power button, the channel+/minus, the band+/plus, the menu and one more time some direct shortcuts to band and channel selection

When the EV800 is plugged for a recharge, the battery status turns to a solid red. When the recharge is finished, the light turns to a solid green. To power the EV800, yoy need to long press the power button more than 1s. The same to turn off. If press on the left CH+ button, you can select one of the eight Vfreq associated with the current selected band. The same for the right CH+ botton (strange to have twice the same fonction). The left Band+ cycles between the 5 bands (race band supported of course). The same for the right Band+….
To enter into the menu, you need also to short press on the menu botton. You can tune Inside: brightness, color, sharpness, headphone volume, the power off settings, and the language (English/Chinese). To increase a value press Band+ and to decrease press CH+.

Good news, you can install it on classic camera tripod via the “kodak” mount.

-Weight

null

null

null

A little bit more than 400g… a little bit heavy for a foamless system IMHO.

null

Disassembling

null

A MST706 as MCU. A serial port seems to be here too.

null

Good news, the LiPo can be replaced easily, just disconnect and replace.

UNBOXING & TESTING

The general LCD screen offer a pretty good image sharp and precize. A large improvement versus the VR007. The immersion feeling is great… I like. The RX sensitivity is also improved IMHO versus the VR007, probably a -95dBm VRX Inside. But as expected without any foam, the EV800 starts to be painful for cheek after few minutes. You need to tune perfectly the headstrap to offer a good VR800’s positionning while not being too much painful for cheek. Definitively, the first mod to do is a basic foam installation. Another negative point, concerns the autoscanning/seach button. I found, the procedure stop every 1 or 2 channels… Of course most of the time on a black or whitesnow screen. It seems the threshold set to detect energy or not in a band is too low. By consequence too much false alarm…. In pratice, you will have to press a lot on the search button…. not sure it’s more efficient than a manual search.

CONCLUSIONS

The EV800 represents a major revision of the VR007 mainly in terms of LCD screen, Fresnel lens, builtin LiPo, RX sensitivity and quality build.Sold just 5 USD more than the VR007, the EV800 is 100% sure more interesting to pick up than the VR007. Price are more or less competitive with the Quantum V2. Anyway, the absence of a piece of foam for confort is a real drawback. It represents the first mod to do.

PROS

+ Good 800×480 LCD screen with good brightness/sharpness
+ Much more precize than VR007
+ Good RX sensitivity
+ 40CH 5.8G VRX
+ General quality build
+ Large and builtin 2000mAh LiPo

CONS

– No foam/sponge rubber facial protection
– No Fresnel lens distance ajustement
– Autoscanning stopping almost at every channel
– No Rotation/Aspect ratio features
– No AVin/AVout
