I broke my USB port on my Omnibus F4 Pro, and i dont know how i can connect the FTDI-Adapter to the board.
If i google a How-To i can only find some "normal" F4 boards.
Here is a Sketch of my board:
and here is my Adapter:
i hope someone can help me.
I've never tried it, but I can make an educated guess... Pick a spare UART on the FC and connect Rx to Tx, Tx to Rx and then ground and 5V anywhere on the board. I don't think you need to worry about the DTR and CTS pins on the FTDI. In Betaflight go to the ports tab and enable MSP on the UART you connected to.
