There are many AIO FPV setup out there that includes both camera and VTX. Today we are testing the Eachine EF-01.
Get your Eachine EF-01 from Banggood.
In order to understand some of the specifications, please learn about the basics of
Spec of the Eachine EF-01
- FOV 150 degree (horizontal)
- Input Voltage 3.0 – 5.5V; 380mA @3.7V
- 5.8Ghz 25mW 40 channels (1sec button hold to change channel, 2sec hold to change band)
- NTSC/PAL switch-able (5sec hold)
- Weight: 8.7g
The screwed-on lens is very long compared to other AIO mini cameras. On my unit, the lens seems to be glued so it might be a problem if you need to adjust focus.
The protective case is metal and very strong (also heavy).
The coax cloverleaf antenna is VERY stiff and tall. I don’t quite get why they make it this way, simply taking up too much space, and easy to damage the antenna (because it won’t bend in a crash).
At over 8g of weight, it appears to be a bit too heavy for Tiny Whoops or even other bigger brushed micro quads. So how about removing the case?
It’s easy to remove the metal case, just unscrew and it slides right off. Weight without case: 6.7g
No Power Filter
When I tapped power off my lipo on my micro quad, video was so noisy it was un-flyable. There seems to be very little to none power filtering on the VTX. I had to use the regulated 5V on the FC to get decent footage.
Video Quality Testing
On the left you see the Eachine EF-01, and on the right is the FX797. You can clearly see that the picture is so much better, sharper with more vivid colour.
However the FOV seems to be smaller than the FX797.
Also the light handling isn’t very good, pretty poor WDR.
Here is some footage comparing the two camera.
DIY: Replace Cloverleaf Antenna
I really don’t like the long stiff antenna, so I replaced it with a shorter whip antenna. It’s also nearly a gram lighter! Weight with whip antenna: 5.9g
- $10 to $20 cheaper than most AIO FPV combo
- Built-in right hand Cloverleaf antenna
- 40 channels over 5 bands including race band, easy to change channel with a switch
- Allow changes of PAL/NTSC video mode
- Sharp, good quality image from 800 TVL camera
- The Strong metal case might be useful to some people
- Smaller FOV and less fish eye effect, I think some people prefer this over the TX797
- I don’t like the its WDR and light handling, seems to be changing way too frequent for me
- Too heavy (original weight 8.7g, without case 6.7g, with whip antenna 5.9g)
- Can’t be powered directly from Lipo, due to motor noise interference
- Vulnerable and excessively long antenna
The Eachine EF01 offers very nice image quality, but it’s heavy and wide dynamic range isn’t ideal. Along with some other disadvantages, I don’t think it would make a good candidate for brushed micro quads. But I think it might make a good camera for fixed wing or other RC applicaitons though.
How did you replace the antenna? Mine is breaking and I’m looking to replace it soon
the spec says there is Audio fequency, is there a built in microphone in this camera?
no it doesn’t.
Hi oscar.. i have one of this.. but i want to take the camera out of the vtx.. i wonder which one is the plus n minus for the voltage input.. and which is the video out … can you help me find out?
I planned on using the cam for other vtx..
you should be able to measure the voltage of the 3 pins with multimeter?
I wouldn’t know without taking one apart…
I have take it apart… one pcb belongs to the cam.. and the other is the vtx (that i think)… i see there are 3 pins on the side… and another 3 pin conecting both pcb… i wonder which one is the video out.. and the plus and minus…
Ciao, thank you to share your review.
Could you explain how to reduce noise?
What you mean with “I had to use the regulated 5V on the FC”?
I’m using this cam on H8 mini and noise is too much to enjoy fov flying.
search for some light weight 5V voltage regulator with filter :)
Seems they have fixed the noise issue on the recent batches. I currently power it direct from 1s lipo without noise. Now my problem is i have some serious jelloing going….
Just seen there is a lighter similar priced eachine cam with vtx, search for Eachine QX90 on banggood and the qx90’s camera is available seperately (wish I’d spotted that before buying the one in this article)
Do you think this camera is ideal for a brushless 2.5″ micro build? Seems like the best option for its price.
yea i think that should work fine on a brushless, if a couple of grams don’t matter that much, as well as providing filtered 5V for it.
