The XJT telemetry transmitter module fits JR style modules, including the FRSky X9D, Horus X10 or X10S, and the 2019 versions of the X9D radios. This will allow you to run in D8 mode in addition to standard D16 mode.
Features up to 16 channels and s-port for duplex communications with X series receivers. (Only certain transmitters are capable of sending 16 channels to the XJT, which include FRSky Radios.)
Compatible with both the V8, D, LR and X Series (telemetry) receivers from FrSky.
You can also add the XJT to the back of your FrSky Taranis transmitter for 32 channel in totals when running in D16 mode!
