Raceflight FC Version?

[Lillios]

Hey.
I have bought a used FPV quad.
Im trying to connect it to betaflight, and it wont work.
Just says "Faild to open serial port".

I can connect to my other Quad, Wizard x220, and it work fine.
I have tried to reinstall the drivers, but that did not help.

What im i doing wrong?

Also, im trying to figure out how to find what "model" it is on the flight controller.
It does look like the Revolt V3.
But it does not say "RF" on the card?
And on the back it only says "Raceflight"?

Any ideas?
I dont want to set it in DFU mode, when i dont know the exact version of the FC?
Or do they use the same Firmware?

Its not easy to take any pictures of the board without taking everything apart.

I managed to read out the Processor of the FC.
Its not the best picture, but it says:
ARM2
STM32F.405
RGT6
GH21K VQ
CHN GH 637

So its a F4?
But what versions on Raceflight FC's uses F4?

Hope this helps.

Need to dfu flash firmware

Flash cleanflight 2.5 if you can find it for your board. You'll get some propwash, but a very solid flying machine.

It's a Revolt by the looks of it, so it'll use FlightOne firmware. Here's a link to the Configurator anf the firmware downloads

Download - FlightOne
