Evening all,

I'm just building a NewBeeDrone CineMah and in my haste and with hindsight, I could have chosen a more suitable flight controller. But anyway, I have a Mamba Basic F722 Mini Mk 3 which I want to use with a Vista Pro Nebula and DJI transmitter. This FC doesn't have a pad titled SBUS, and apologies if this is noob question, but can I use the UART5 F Port pad instead?

If so, will that require some changes to the parameters? I've not decided yet whether to give INAV a try yet as I'm fitting a GPS unit and hope to have some rth failsafe.. I still haven't had the balls to try GPS rescue in BF on 2 of my other quads which have GPS..

It also doesn't have a 9v output so I'm having to take VBAT, which I'd rather not as I'll be running 2 x 3S Lihv batteries so I'm hoping I didn't spike it out (will fit a capacitor).

Thanks in advance.

Peter.

An SBUS signal is inverted so the FC has to uninvert the signal before it can decode it.

Only F4 FC's need a dedicated SBUS pad because the F4 MCU can't natively uninvert the SBUS signal, so the signal going into that SBUS pad first passes through a hardware inverted before going to the F4 MCU. F7 FC's don't need a dedicated SBUS pad because the F7 MCU can natively uninvert signals and don't require a hardware inverter, so you can connect an SBUS signal to the RX pad of any UART on an F7 (and F3, and H7) FC.

Once you have wired the SBUS connection to a spare unused UART, just configure that UART for "Serial RX" in the Ports tab. Make sure you only have that one UART configured for "Serial RX" (i.e. switch "Serial RX" off for all the other UARTs).

Thanks so much for that, is much appreciated..

Peter.
