DJI CP.AL.000005 Overview

  • 1Description

The Lightbridge 2.4G Full HD Video Downlink with OSD and Control from DJI is designed to provide a complete FPV wireless relay solution, combining the video downlink, OSD (on screen display) data, and control signal in one system. It features two key components, one for the air end and one for the ground end. The air end component is a module that installs in or on the aircraft and features HDMI and composite video inputs. It also communicates with the flight computer, sending pilot inputs from the radio controller (transmitter) to the flight controller and receiving flight data from the instrumentation for the sake of the OSD. The air end module can also send a control signal to the gimbal for in-flight operation of camera movements.

The ground end component features the form factor of a wireless router. It can be battery powered from an internal 4000 mAh battery that lasts up to 4.5 hours or an external 3S to 6S Li-Po battery, available separately. To operate the aircraft, the system allows you to use your regular 2.4 GHz radio controller and will also receive a gimbal control signal. To view the video feed and OSD overlay you will need an Android mobile device running the Lightbridge app, a free download from DJI. There is a powered USB port on the ground end to connect your mobile device and keep its battery from running down.

Requires Compatible Flight Control System
Lightbridge works with select DJI multi-rotor flight control systems. Compatible flight controllers included: A2, WooKong-M, Naza-M V2, and Phantom 2
HDMI and AV Video Input with Full HD Transmission
The air-end module supports both analog composite and HDMI signals. When using HDMI resolutions of to 1080p at 30 fps can be transmitted
Low Latency
The video link features a latency of approximately 150ms. This makes the system suitable for FPV flying and aerial videography, where real-time feedback is essential
Up to One Mile Wireless Range
The air end module supports a line-of-sight range of up to a mile, depending on environmental conditions and other variables

Note: By law, in the U.S. and many other countries, pilot visual contact with the aircraft must be maintained at all times.
Built-in 2.4G Remote Control Link
Not only does Lightbridge relay video and OSD data back to the ground end, it also provides a way of extending the link between the transmitter (hand-held radio controller) and the aircraft. Plus, the Lightbridge system relays the gimbal control signal
4.5 Hour Battery Life for Ground End
The ground-end features a transceiver that is similar to a Wi-Fi router. It can be wall-powered, but since you will most likely be using it in the field there is also a built-in 4000 mAh battery lasting up to 4.5 hours. The battery can be charged with the supplied AC adapter or a 3S to 6S Li-Po battery
USB 2.0 Port for Mobile Device
The USB port allows your Android smartphone or tablet to communicate with the ground end, and will display video from the camera on the mobile device's screen. Plus the port is powered so you don't have to worry about running down your device's battery. For Android users it is recommended you have Android 4.1.2 or above
Built-In OSD
The OSD (on screen display) is natively part of the Lightbridge system meaning a separate iOSD module is not required. The OSD supplies telemetry data supplied by the flight computer, including, attitude/relative position, height, distance, horizontal and vertical speed, flight mode, power levels, signal strength, and GPS strength
Anti-Interference Technology
Up to 8 downlinks can be connected for parallel streaming. Each can work independently without interference as long as proper spacing is maintained between them
Multi-Device Operation
A single air system can transmit to multiple ground systems, sending video to multiple screens at once. One ground system will send the control signal while additional ground systems receive the video signal only
Advanced Security
Guards against third-party interception of the wireless link or loss of control over the aircraft to a third party. Plus encryption can be setup through the Lightbridge app

DJI CP.AL.000005 Reviews

Lightbridge 2.4G Full HD Video Downlink with OSD and Control is rated 3.5 out of 5 by 4.
Rated 2 out of 5 by from Not a good value I bought this for my Phantom 2 because I thought it would help making video composition better then the DJI AVL58 analog unit I had and also improve the range, but it really did neither. It did lighten the weight by eliminating a lot of extra gear like the iOSD, the big DJI video transmitter, wire hub and cables, but the big and bulky receiver made the controller difficult wheel. The video looked good, but not full 1080P and the video delay was nearly a full second, so that made it difficult when flying low and fast. I don't think for $ its worth it, so I returning it and RE-PURCHASED the AVL58 and ect. I hope that DJI upgrades and reduces the size and price to about half, and maybe I would reconsider buying it again.

Rated 3 out of 5 by from Still has a few issues CONS1) DJI Lightbridge with newest firmware update does not support 1080p 30fps as described on BH Photo and DJI website. It currently only supports 720p wireless, which is also stated in the release notes for the most recent firmware. DJI hopes to have a fix soon, but presently stuck at 720p an no ability to go revert back to old firmware to 1080p. If you don't upgrade firmware then there is a chance you will have 1080p out of the box with slightly older firmware.2) No mentioned on DJI or BH Photo website that configuration options cannot be set in the PC software and user must purchase or own an Android device with DJI app installed to access configuration options for the Lightbridge, such as changing refresh frequency, change display settings, show OSD, or to remove warnings. (iOS is not supported yet as of 8/2014 but beta testing is supposedly going on)3) The wireless latency is stated by DJI website as 80ms, which was not even close to what was experienced. Latency in the wireless video is typically 200ms which could sometimes go to about 500ms in smooth setting with units only 10 feet apart. This was tested with various cameras and with both USB-based connection for video to Android device and HDMI based output to a TV Monitor.4) Unit is not designed to be used as a stand-alone HD Tx/Rx wireless video, although it can support this on HDMI output only. Out of the box, you will get a warning on HDMI display that Controller is not connected and see an On Screen Display for their DJI aircraft. Although the warning and On Screen Display can be turned off inside the Android App, it only affects the output on the HDMI port and the warning will still be displayed on the Android device. If you will exclusively use an HDMI monitor and never an Android to display live video, then you could technically use this as a standalone Tx/Rx, however you will need access to a PC for firmware updates and access to an Android device to make configuration changes.5) No ability to set HDMI output at 720p to anything other than 50Hz or 60Hz. I had a small 720p TV HDMI monitor that refused to show video because of this. PROS1) Unit is 2-way and the ground station of Lightbridge can transmit the R/C commands over the same 2.4Ghz link to the aircraft. In other words, you can connect the PPM stream from up to two R/C transmitters on the ground to the base unit and it will transmit those commands to the Tx in the Air at the same time while receiving video from that Tx.2) You can use the PC software on the ground unit to set which PPM channels you want assigned to which channels on the final SBUS stream onboard the aircraft. This allows you to have one RC to control the craft and a second to control the gimbal and camera.3) Tx is very small and fan is barely audible, but can get quite warm.4) Almost all information visible in DJI iOSD mini is visible on the Lightbrige OSD, so you can get rid of the iOSD mini from your Phantom. By going to Lightbridge, you lose the heading in degrees, however it is replaced by a mini map in the lower right corner that works pretty well to get you home and show orientation. Battery voltage is sadly changed to just a percent left.5) For the first time ever, you can see link quality in the upper right when OSD is enabled. Very nice to know when you are at the end of your range.

Rated 4 out of 5 by from I Like them I own one set of them and it works great, better than others and you can also show clients a solo stream throu the HDMI output. Could be better mounting option. I have to build my own to fit my gear.

will this work with an iPhone?
Asked by: Anonymous
When I bought the DJI Lightbridge it could not be used with an iPhone. I purchased an Asus Android tablet for this purpose. I don't know if the unit will work with an iOs device today.

What all do I need to be able to fly the Hexacopter s900
Asked by: Ray W.
You will still need a flight control system such as the DJI A2 or the DJI Wookong-M. Along with a battery and remote transmitter to control the copter.
