Vtx connection by SmartAudio
If you own any Unify or any other VTx with SmartAudio capability, you can connect it to your Crossfire
receiver as well.
● Select a free output pin capable for SA (check the output map section for available outputs)
● Connect them (Crossfire Tx to VTx Rx/ SmartAudio pad)
Smart Audio or CRSF for the VTx?
Both protocols had their advantages and disadvantages:
● SmartAudio
○ Single wire connection. Saves one PWM output (useful if you got a wing and use
the bst pins for bst)
● CRSF
○ OTA Updates (upcoming)
○ Full y configurable by LUA, Crossfire OLED, FUSION etc.
○ CRSF readout - let you use PITMode on a switch or navigate through the Unify Evo
OSD without the need for a fc, link stats readout with the Unify EVO OSD
