These have installed the latest EU LBT Firmware.
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 hub less digital sensors! Or, connect the new vario, and then connect the old hub to use existing analogue sensors.
S-BUS allows you to have access to all 16 channels. Alternatively, you can use something like the FrSky S-BUS Decoder, this will allow you to add 4 normal servo outputs (PWM). You can also connect S-BUS servos directly to the S-BUS line. Just "Y" in as many S-BUS devices as you need.
Note: This version of the X4R does include the S-BUS output and offers 3 channels via PWM. No PPM output.
Operating Voltage Range: 4V-10.0V
Operating Current: 100mA@5V
Operating Range: >1.5km (Full Range)
