Rotorflight Target
When updating Rotorflight firmware. Please use the NEXUS_F7.
Matching RP3-H ELRS receiver
Any of the Rotorflight receiver protocols can be used with the NEXUS. Radiomaster does have the RP3-H receiver which is a direct plug and play ELRS receiver.
F-Port
Nexus supports F.Port on:
The 'TX' pin of Port A, B or C or by remapping the SBUS to a TX for F.Port.
F.Port is an Unverted protocol over a single wire so must configured with both of these options enabled.
Motorised Tail
To use the NEXUS with a motorised tail the Servo 4 needs to be remapped to Motor 2. This can be done in the CLI using the following command (just copy and past this into the CLI then push [ENTER]).

Wiring
UART ports
All the UARTS on the NEXUS are labeled to match each port. Just enter the function you wish to use for each port such as SerialRx (receiver), ESC Telemetry, blackbox, GPS etc.
