FrSky X4R 4 Channel Receiver with Smart Port
FrSky's X4R receiver features 4 PWM outputs. It has the Smart Port and the traditional A2 port, located on the side of the receiver. A FrSky FBVS can be connected to the A2 port for simple voltage monitoring as well as all of the Smart Port based sensors.
Smaller and lighter than the X6R.
This version of the X4R does not include the Sbus output. This is only a 4 channel receiver. No SBus and no CPPM output.
