Please note, that Smart Audio on this VTX does not work in Betaflight 3.3+ out of the box, you will need to flash an edited 3.3 hex file for your FC, our complete list is here.   We are selling these units at a discount as our next version will support Betaflight 3.3 smart audio.  Otherwise this VTX works just like any other and has an LED display to change channel/power levels the old way.

The VTX[T] is not just another FPV video transmitter, it has been built to pack all the latest technology into a small and affordable package. This is aimed to be a viable alternative to the more expensive TBS unify, or immersionRC tramp video transmitters. This VTX supports a wide range of power input (7-24V), will output a constant 5V to your FPV camera, and is able to switch between 25, 200, 500, and 800mW of transmission power.

In addition to serving the function of a basic VTX, the Chaos FPV VTX[T] supports BetaFlight VTX telemetry allowing you to control settings on your VTX directly from your betaflight OSD. All you need to do is hook up the telemetry connection from the VTX to a spare UART port on your flight controller.

Pitmode functionality is supported which means that if you are flying at a race event, the VTX will power on with a low transmit power, allowing you to test and configure your drone without causing interference to other FPV pilots. Then before you go and race you press the button to enable the VTX to transmit at full power for your race. Of course, if you are flying alone you can disable pit mode entirely.
