VT5804 Pro stackable video transmitter is a copy of the successful RUSH VTX V1. Despite the fact, that it is a copy, there are some differencies. It does not have (at least not stated) audio input or microphone on board. The output power levels are 25/200/600mW. Also it features SBUS input pin so you can control the channel switching with your TX.
Weight without antenna is about 6 grams only. It uses MMCX (micro-miniature coaxial) connector for antenna pigtail. This allows to save space and weight. Look at this size comparison picture between regular RP-SMA and MMCX connectors.
Unfortunately the package includes a MMCX with some linear dipole antenna on the end of the pigtail. It would be better to include a MMCX to RP-SMA or SMA pigtail instead. Or even better to add antenna and pigtail.
There is also no on-board microphoen and no audio input, so not a good new for audio lovers.
