More info

This is the X4RSB receiver from the FrSky S.Port Telemetry X-Series.

It's a easy to use and small sized receiver with 1-3 PWM channels and 1-16 SBUS channels.

You can hook up the 1-3 PWM channels to your servos, gimbals, buzzer etc., where only PWM input is accepted, without losing the 1-16 SBUS channels.


Note: In order to use the SBUS Signal with your Naze32 (rev5) you need a inverter cable, or you can easy make a inverter your self.

The SP F3 already has an built-in inverter for SBUS no external inverters are required.

No modification is needed for CC3D to support SBUS.
