Hello everyone.

I have ordered parts for my first build.
A lovely little 3s Tadpole.

I think I have the wiring done, but I have one issue.
The Mamba F411 AIO 25A only have 2 uart ports, one for the rc and one I'll use for the VTX.
I'd love to be able to control the runcam split 4 from the transmitter as well. 



Any ideas how to handle this?
The wiring diagram from diatone is only for DJI, so I'm a bit lost.
I'm think about doing soft serial, and maybe use RX2 and LED for tx/rx, but I'm up for ideas how to best do this. 

Best regards, and thank you in advance.

The problem with that FC is that it is really sparse with breakout pads and it only has one full UART for the receiver plus half a UART (TX2) for SmartAudio. You can of course remap the TX2 and LED pads to create SoftSerial TX/RX connections to control the camera with, but that leaves nothing for SmartAudio.

So you are going to have to decide what is more important, SmartAudio or remote control of the RunCam Split 4.

Thank you Snow leopard.

This is the 25A version of the mamba board, so i believe it has a full uart port (Tx2/Rx2)

Im considering using that for the runcam, and soft serial the LED to smart audio

I couldn't see the RX2 pad anywhere. In that case you can use UART2 for the RunCam Split 4 and remap the LED Strip pad to a SoftSerial TX connection for SmartAudio.
