FrSky's newest receiver features 16 channels (8 normal pwm outputs and all 16 channels on the dedicated Sbus output). Plus the exciting new Smart Port.
Smaller than the previous 8 channel recievers, but now 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.
A common question we get is how do you get all 16 channels out of the X8R? Well, FrSky has given you options. You can use the Sbus line to access all 16 channels. Using something like the FrSky Sbus Decoder, you can convert the digital Sbus signal to normal servo outputs. You can connect Sbus servos directly to the Sbus line, frSky will have several servo options very soon. Or you can combine 2 X8Rs and output channels 1-8 on the first receiver, and output 9-16 on the second receiver.
But that isn't all the X8R can do. It can also work in "D8 Mode to work with the DHT, DJT, DFT and DHT-U transmitter modules. In this mode you have 8 channels. The neat trick is the Smart Port still works in D8 Mode!
You are probably wondering about the new antennas on the X8R. FrSky refers to these as PCB antennas and report up to a 20% range increase over the standard antennas.
Dimension: 46.5mm x 27mm x 14.4mm (1.83" x 1.06" x .56")
Weight: 16.8g (.59 oz)
Operating Voltage Range: 4V-10.0V
Operating Current: 100mA@5V
Operating Range: >1.5km (Full Range)
RSSI output: analog voltage output (0~3.3V)
All 16 channels require the FrSky Taranis, or the XJT module.
For 8 channels in D8 Mode you can use the FrSky Taranis or XJT, DJT, DFT, DHT and DHT-U modules.
Nice little twist for APM users (or anyone in need for 16 channels mapped to 2 different things)
X8R is 16 channel receiver. But it has 8 pins (outputs only). Using configuration steps provided in the X8R 8 manual you can select, whether on the 8 pins you going to have Ch1 through 8, or Ch9 through 16.
Simultaneously you can have SBUS-to-CPPM converter
connected to SBUS port which will output all 16 channels on the CPPM end of the converter.
Now, for APM specific setup, as you mentioned, connect the SBUS-to-CPPM converter to APM on pin 1 and short pins 2&3. This way your APM will get all 16 channels from X8R (but APM will only use ch 1 to 8 which is max for APM. APM will ignore ch9 to 16).
Then you configure X8R to output Ch 9 to 16 on the X8R pins (Mode 4), and you can connect any other devices you want directly to X8R pins.
