FrSky X4R-SB - 3/16 Channel Receiver w/ SBUS

Quick Overview

The FrSky X4R-SB - 3/16 Channel Receiver w/ SBUS
In Stock


FrSky's X4R-SB receiver features 3 PWM outputs (normal servo) and 1 Sbus port that carries all 16 channels.  Plus the exciting new Smart Port and a traditional A2 port are all 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 new 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. 

SBus allows you to have access to all 16 channels. Alternatively, 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.

Note: This version of the X4R does include the Sbus output and offers 3 channels via PWM. No CPPM output.
