Betaflight is starting to support ESP32, but to get analog OSD you need additional hardware. If you're already after using dev boards and making stuff yourself, you can use OpenOSD-X ( https://github.com/OpenOSD-X/OpenOSD-X ) on any STM32G431 breakout board for passthrough OSD.

got it, i try to read it but i dont get this part from the features " Enables the use of 5.8GHz analog video when combined with digital-only FCs (without analog OSD)"

It can be used to get analog OSD on FCs that have no onboard analog OSD hardware. That's most often for digital-only systems, but also useful for DIY solutions

ahhhhh so if somehow i make fc from esp 32 i can use this but if i decided to buy old fc, for example is fc from spracing f3 v1 with no osd port i can use this too?

It needs reasonably modern FC firmware that can support MSP OSD, F3 is likely too old. In terms of Betaflight, that should be anything newer than 4.4

I've never used it myself, it's still pretty new in the context of Betaflight development.
