It's labelled as SBUS on the connector. It's either hardware inverted or uses the inversion pin (which is already defined)

are you sure this works? just asking

Yep, all tested. It's a bizarre thing to do, but its what betaflight does and the RTF kits rely on this
add UART6 and VBUS to BETAFPV F405 add alt config to BETAFPV-F405 to support RELAY2 instead of UART6_TX as per betaflight enable SBUS input on BETAFPV-F405 on UART5_RX enable IMU temperature calibration for BETAFPV-F405
