Hi again 
I bought used mentioned drone in great shape (2h of flight time) it's my second one after Tinyhawk 2 freestyle so I have few questions since it's my first CRF system and there are so many information flying around and it's gets confusing I have all connections worked out I have gimbals recognized in Betaflight Rx is binded (Jumper Tlite with Tracer nano)  no errors on startup GPS seems working fine on a bench etc but I have (had) new Immersion RC Tramp nano vtx which I accidentally burned by connecting it to Vcc instead of 5v and powering it up on 4s there comes reading manuals with understanding (it worked on full charged 2s surprisingly?) but my question is where on board I should connect "Tel" white wire from vtx to have it show on OSD?
For time being ( ordered new Tramp) I'm using Vtx from my Tinyhawk for its maiden but there is also "Audio" wire and I'm not sure is that SmartAudio and should I use it with Tracer nano somehow?

I would be very thankful for some clarification,thank you in advance!

The Telemetry In/Out pad on the ImmersionRC Tramp Nano VTX needs to be connected to the TX pad of a spare UART on the FC. The you need to configure the Peripheral for that UART in the Ports tab of Betaflight Configurator to be for "VTX (IRC Tramp)".

I believe the "Audio" pad on the TinyHawk 2 Freestle VTX is SmartAudio. Like with the Tramp Nano, you need to connect that to the TX pad of a spare UART on the FC and configure the Peripheral for that UART in the Ports tab of Betaflight Configurator to be for "VTX (TBS SmartAudio)".
