I have an old FC from an Eachine Wizard X220HV with a busted ESC on the stacked ESC. I want to use this stack for an FPV plane, as I only need one of the 4 ESCs so this should work nicely.
Problem is, this board is a custom board by Eachine with their own firmware on it. I don't know which version of Inav to flash to it as I can't identify which board this is. It's got OBSD F4 V5 on it, which I thought would be Omnibus F4 V5, but I don't see a V5 option in the hardware list on Inav Configurator.

Can someone help identify this board or tell me which firmware version to flash?

Looks like this FC uses OmnibusF4SD firmware target on Betaflight. You can confirm that just by plugging in to BFC and looking to the upper left. You should see the FC target currently on the FC.

So now you want to load iNav. According to the iNav wiki, they recommend using the OMNIBUSF4PRO_LEDSTRIPM5 for clones.

Thank you! I'll confirm in Betaflight and check the recommended firmware in the link.

Success! I flashed the OMNIBUSF4PRO_LEDSTRIPM5 firmware and all seems okay in Inav.

Very good. I think the main difference was the resource assigned for SD card. And double check that both UART 1 and UART 6 are functional.
