This is a 4-wire camera lead compatible with many different common FPV transmitters, most notably the 400mW, 700mW, 800mw, and 1500mW 1.3GHz, the 1500mW 900MHz, and the Lawmate 1000mW transmitters previously sold here at ReadyMadeRC.
If you've purchased your transmitter elsewhere, please verify your TX uses the same connector shown in the picture. This is not compatible with the smaller transmitter connectors such as those on the 500mW 900MHz and 300mW 1.3GHz transmitters.
Total cable length of 12", terminated in two male servo connectors: one with video, power, and ground for video, and one with audio, power, and ground for audio. Note that this cable will supply the battery voltage directly to the components, so if your cameras require 5v you will need to insert a regulator in the line before it gets to the camera.
This cable is ideal for connecting your transmitter to the Eagle Tree OSD's, DragonOSD, or RangeVideo OSD, or nearly any combination using some combination of the new ReadyMadeRC interconnects.
