Emax mini Magnum 2 Crsf compatible

Hi, i want to run crossfire on my emax mini magnum 2. I am not able to run IT of the FC because it only has one spare UART. Would i Berlin able to use the port for the leds and idé softserial to make it work for crossfire?
Thanks in advance

I seem to remember(I could be wrong) that you can run Crossfire in SBUS mode so that you then only need the one wire from the Crossfire receiver for signal. In fact, a quick google shows this… Setup Crossfire to Output SBUS - Oscar Liang
