Eachine Light L250 5.8G 250mW Video Transmitter Review

Plug in FPV transmitter for GoPro Hero 3(+)

Splash

Introduction

The Eachine Light L250 is a 250mW 5.8Ghz video transmitter that is designed to work with the GoPro Hero 3 and Hero 3+ cameras. It has mini USB and Micro HDMI connectors that allow it to plug directly into the GoPro and doubles as the attachment point, securely holding the transmitter in place. Banggood sent me a unit to test out and see how well it worked.

Specifications

  • Voltage: 3.5-5.2V
  • Channels: 32
  • Bands: A,B,E,F
  • Output: 250mW
  • Current: 360mAH
  • Weight: 7g
  • Size: 40.8 x 21 x 8mm

What's in the Box

Inside the box, you'll find the transmitter, audio/video and power cable, and the manual. You'll need to provide your own 5.8Ghz antenna and a 1S Lipo to power the transmitter.

Installation

The manual is short and sweet as there is not much needed to say. It's designed to plug directly into a GoPro Hero 3 and Hero 3+ cameras. The alignment was perfect and once plugged in the connection is tight and secure. I have no worries about vibrations or any jarring that would cause the transmitter to become unplugged. The power connector lead is not very long so the best bet is to Velcro a 1S 350mah Lipo to the back of the GoPro. It would have been nice to draw power from the GoPro battery to power the transmitter, but it's not that much of a hassle to use an external power source. The transmitter is the same height and depth as the GoPro, but it extends the width by about 11mm. Even with the extended width, it still fit into one of my old GoPro camera gimbals. It may not fit others however and you will likely need a 90 degree antenna adaptor to make it work. If using with other cameras, there is an A/V connection via the cable.

Operation

Using the transmitter is simple. Just plug it into your GoPro or connect the A/V cable to a camera and power it up with a single cell lipo. An LED status light will turn on. You can change bands and channels easily by pressing the push button switch near the bottom. Press and hold the button for 3 seconds to change the band. Press quickly to change between the different channels. I chose to use my Black Pearl monitor with Diversity Rx to receive the signal. It came through clear and with no interference although signal quality is dependent on many different factors. It was now time to put it in use.

Jim T Graham and I were heading to the field to drive some FPV trucks for an upcoming video podcast so I thought this was a perfect opportunity to test out the video transmitter. I mounted the GoPro with Velcro to a carbon fiber plate from ReadyMadeRC on an Axial Wraith truck. The antenna was straight up in the air and I was ready to go. I connected my Zeiss Cinemizer Video Goggles to my receiver and we both took off in a field. I had the monitor/rx on the ground and after about 100 feet or so the video feed dropped out. I knew what the problem was and picked up the receiver to get a better line of sight with the transmitter and the signal came back. I was able to drive around the field with no further issues and then we decided to head for the woods and a trail.

In the trail there were many obstacles and barriers for the signal to pass through. It held up surprisingly well, but eventually yielded to the dense foliage. 5.8Ghz is just not great for cutting through barriers, but if flying in the air or using with a clear line of site, this is a respectable unit.

Conclusion

The Eachine Light L250 5.8G 250mw Video Transmitter performed as well as any other video transmitter I've used in this power class. I really like the size and weight and the fact that it plugs directly into my GoPro. It makes for a super simple FPV setup. The channels are easy to change and it runs for a little over an hour on a 1S 350mAh lipo. At a little under $40, I think its a great value.

Pros

  • Compact and Lightweight design
  • Directly connects to GoPro Hero 3(+)
  • Works Great

Cons

  • Would have been nice to get power from the GoPro battery
  • Cannot use the GoPro Protective Case

It would be nice to know what is the maximum range of this one. Certainly a really nice product.

Its hard to determine the maximum range of video transmitters, there are a ton of factors in play, such as antenna used, environment noise, receiver antenna, location, etc. I saw a video of someone that went out something crazy like 30 miles on a 200mw 5.8 video transmitter.

Is the gopro giving out 3.7V at usb port? Anybody tried yet? If so, it would be easy to mod the transmitter for getting powered by gopro usb port...

I'm pretty sure you need to have an Amature Radio License to use anything over 25mW in the US. I could be wrong on that number, but 250mW is likely over the limit.

No,the gopro can't give out 3.7V at usb port. should buy extra 3.7V 350mah lipo

I would have hoped the HDMI can give it enough power to make it work

Range


In my testing on a quad with a Ibcrazy antenna I was only able to get about 500 feet before snow took over.Less range than my TS5283(200mw).Its great for close in stuff and very portable but a little disappointing for distance.

Are you sure it won't work with the GoPro skeleton case?

I haven't seen or used one of those so I wouldn't know.
