SBUSo port no 5V power

#1

SBUS wiring frsky x4r reciever wiring needed

#2

Wrong port. Plug the X4RSB into the “RC IN” port next to the motor outputs.

Idk what the SBUS port on top is for, but I think its “SBUSo” for “SBUS Out” which could run an external device like a gimbal.

I just setup a X4RSB and ran into the same thing. It works plugged into RC IN

S.Bus RX goes to RC-IN same as PPM.

S.Bus Out is for S.Bus Servos, ESC’s etc…
