Thanks, I read the vtx wiki. But it’s a flight controller problèm. I dont know how powered the vtx with mamba f405 mini mk4.

I messed up on the H743 with VTX power so I could have made the same mistake on the F405 mini. Which target are you flashing? is it the 2022B?

Yes, I screwed up. Fix is here: Mamba F405 2022 VTX Power by andyp1per · Pull Request #22976 · ArduPilot/ardupilot · GitHub

Can you try this firmware?

If you can let me know today that would be great as I can get it on the dev call this evening. You might have to set RELAY_DEFAULT = 1 to get it to work (or at least if this is set to 0 after the upgrade set it to 1)
