FrSky has developed new firmware for the X4R-SB that allows it to run CPPM outputs by placing a jumper across signal pins 2 and 3 during binding. This version is without pins allowing for a compact and custom wiring. This receiver is de-pinned from the factory.
The X4R-SB-CPPM receiver features 3 PWM outputs (normal servo) and 1 Sbus port that carries all 16 channels. Plus the Smart Port and a traditional A2 port are still located on the side port of the receiver. A FrSky FBVS can be connected to the A2 port for simple voltage monitoring.
Smaller than the X6R, but still packing 16 channels and the Smart Port that supports the new hubless digital sensors! Or, connect the new vario, and then connect the old hub to use existing analog sensors.
A common question is what can the SBus port do. First off, you can connect it to many flight controllers via a single connection, and now you have access to all 16 channels. Or, you can use something like the FrSky Sbus Decoder, this will allow you to add 4 normal servo outputs (pwm). You can also connect Sbus servos directly to the Sbus line. Just "Y" in as many SBus devices as you need.
