TEST: Eachine EV100 DVR module

Drone News

Recommended Posts



The Eachine EV100 is probably the cheapest binocular FPV goggles recently introduced. Here is the dedicaced external EV100 DVR module for them. The module will be connected by a jack cable for the AV signal and by the balancer plug of the EV100 to power the module. Let’s discover this module.



+ 1 x EV100 DVR
+ 2 x 3.5mm to 2.5mm jack cable (4 positions)
+ 2 x Double side tape
+ 1 x Instruction manual (English)


Like the HMDVR and the Eachine Pro DVR, the EV100 DVR module can record with three different output resolution. Clearly the highest is playing with interpolation from a D1 NTSC or D1 PAL source. It’s mentionned to write in 720×480 for the D1 resolution, probably associated with an NTSC camera source.


Three buttons can be found on the front panel. The left one (<< backward) trigger the DVR recording. When pressed, the red light will flash and become solid with the recording is stopped. The central button when long pressed in DVR mode will pop up the DVR settings menu. null


The 2.5mm jack port represents either an AVin when the switch is in “1” position or an AVout when in “0”. To record a file, the module must be in “1”. To replay a file or to change a settings, the switch must be in “0”. in “0” position, you must click on the right joystick of the EV100 more than 6s (until the third beep) to display the DVR’s OSD informations.


The microSD port where is class 10 card id prefered.


The module can be powered via a microUSB port or by a 2S balancer plug.







For the connexion, it’s super easy… power the module with the remaining balencer plug of the EV100’s battery. The AV connexion is done via one the two jack 3.5mm to 2.5mm cable.



In order to measure the amount of cropping, thanks to betaflightOSD, some OSD informations are spread in the four corners of the screen.

PAL source

PAL layout


Files are recorded in 720×480@25fps for PAL source. Well if the AV source is present before to turn on the DVR, files will be recorded in 720×576@25fps.


Here is a screenshot of the Aomway rendering. We can guess at least partially the top four informations on each corner.


and for the corresponding EV100


As you can see, the EV100 crops some top and bottom informations. But let’s check if the DVR module standlone don’t introduice extra cropping.

This videos shows the recording of the PAL source with EV100 DVR plugged on the EV100

compared with the Aomway Commander V1 builtin DVR on the same PAL source…

Clearly some informations are missing for the EV100 recordings… but some were already missing for te AVout.

So I decided to plug the EV100 DVR on the ACV1…. and here again the bottom part is cropped….

Definitively, the EV100 DVR has probably the old HMDVR firmware cropping PAL sources. More you can guess some diagonal lines, some interferences.

NTSC source

NTSC layout


Same 720×480 resolution but this time @30fps


Let’s check the EV100 recording for this NTSC source

versus the ACV1

Good news for NTSC…. no extra cropping in the recording…

The DVR menu is a fax-simili of the HMDVR one …. exactly the same settings and option




Clearly the probability is high to be able to flash the HMDVR firmware fixing PAL issues.


A pretty good DVR module super easy to plug to the EV100 requiring 0 soldering job. More it’s also compatible with most FPV goggles as soon as there is an AVout with a jack plug. My concern is about PAL recordings cropped for the bottom part. It will be main probably fixed by a firmware update (to be inserted in the root folder of the microSD card)


+ Plug and record
+ Playback functionalities
+ Light
+ 3 records formats
+ HMDVR based
+ Compatible with a lot of other FPV goggles
