While the X6R is no bigger than most other 6 channel receivers, it has much more capability. The Smart Port supports the full range of hub-less sensors as well as the older hub analog sensors and the A2 port on the bottom allows you to connect an FBVS-01 battey voltage sensor for basic external voltage monitoring by pulling the jumper out if you prefer that to the integrated telemetry.
Six standard servo outputs are by the X6R and you can access all 16 channels by using the S.BUS line with S.BUS supported servos or use a FrSky S.BUS Decoder for the full 16 channels.
The X6R is also backward compatible! In D8 mode it works with the DHT, DJT, DFT and DHT-U transmitter modules. In this mode you only have access to 8 channels but you still get to use the new Smart Port and digital sensors!
This is the perfect receiver for the FrSky X9D Taranis, with its built in XJT Module or any of the D8 systems to take advantage of the new digital Smart Port sensors.
