ImmersionRC EzUHF 433MHz Direct Fit JR MODULE for the 9X / 9XR / Taranis

EzUHF has made it even easier to fly with long range UHF, with their plug and play Module.

The long-awaited EzUHF module is here, compatible with most radios which use the 'JR' module standard, including the 9XR and the new Taranis. Same features as its big brother, but without the cabling, or external batteries.

Robust FHSS link

The robust FHSS (Frequency Hopping, Spread Spectrum) link hops to a new frequency every 22ms. This increases the robustness of the link, and makes it immune to most sources of interference. A GFSK (Gaussian Frequency Shift Keying) modulation scheme reduces unwanted harmonics, normally present with traditional FSK modulation.
Power Boost Switch
A transmitter-mounted switch controls the power level, allowing an additional boost to get out of trouble.

USB Port

A standard Mini-A USB port provides a connection to a PC, for firmware upgrades, system diagnostics and configuration. There is no external hardware required for firmware updating.

Head-tracker Compatibility

A 4-pin Mini-Din connectors provide the connection to the R/C Transmitter, and also to a compatible head-tracker. Even radios which hadn’t previously supported head-tracking can now be used.


The EzUHF transmitter requires a license to operate in most countries, an Amateur Radio license is required.

EzUHF 8 channel diversity receiver

The EzUHF 8 channel diversity receiver is a compact 8 channel receiver for use with the ImmersionRC EzUHF system. It can provide long range control of your FPV model with the robust interference rejection that diversity antennas provide.

Compact Long-Range R/C Receiver
Ideal companion to the EzUHF transmitter. Sensitive receiver, with twin antenna inputs, in a diversity configuration. Fits the most slender of glider fuselages.

Interference Rejection
Each antenna input contains a 7-section ceramic low-pass filter, which silences interference from nearby high-power video transmitters on 900/1.2/2.4/… bands. Attenuation at 900MHz is > 40dB, at 2.4GHz > 75dB, right at the antenna input.

Mikrokopter Compatibility
Programmable MK mode, emits raw PPM on a chosen channel. The EzUHF Rx is an ideal receiver to use on Mikrokopters used for longer-range flights.

The ceramic filtering is a huge benefit on a small MK frame, which has a Video Tx antenna nearby.

EzLink connection to an EzOSD
No more guessing! the EzLink cable connects the EzUHF to an EzOSD on-screen display. All critical parameters are sent to the OSD, which displays them live on the display and downlinks them along with the antenna-tracking telemetry.

A ground-based EzAntennaTracker displays the parameters on its LCD display, and the ImmersionPlayer application plots them on its Google-Earth™ overlay.

* Why ‘Bi-directional ready’?: The EzUHF Transmitter is a full transceiver, i.e. it includes both transmitter, and receiver hardware. The 8 Channel receiver is also a transceiver, so both are capable of bi-directional communications. Firmware to take advantage of these capabilities will available in the near future, both are field-upgradable using a std. USB cable.

ImmersionRC iTelemetry dongle

ImmersionRC's new iTelemetry Dongle, a telemetry interface for smart-phones and tablets. The handy little dongle allows users to view critical information such your model's position on a live map, Battery status, Uplink status (EzUHF required), Altitude, Distance and much more.

The ImmersionRC iTelemetry dongle connects between your A/V receiver's output, via a standard 3.5mm 4-pole jack, and your smart-phone or tablet's headphone/mic input.

A unique real-time telemetry decoder application, freely downloadable from either the ImmersionRC website, or the Apple AppStore, may be loaded onto your smart device. This APP shows Real-time updates of telemetry data, including positional status (distance, altitude, direction, etc.), EzUHF uplink status (RSSI, Link Quality), and battery status (current, voltage, mAh consumed). Useful for long range flight to estimate link margins, battery duration. Etc.

The current position of your model is shown as a trail of 'breadcrumbs' over a map, which can show either a road-map, satellite image, or a hybrid of the two. A recovery aid for lost models shows the model's last known position, along with the position of the smart-phone/tablet. Connect the dots to find the model, even in long vegetation (corn fields for example). Very useful when combined with recent FatShark goggles, with built in DVRs. Replay the video recorded during a flight through the telemetry dongle to locate a downed model

A Headphone output enables audio alerts from your smart device to be heard by the pilot, or simply to listen to loud techno-music while racing down a mountain valley at a few inches above the ground. An Adjustable 'thumbwheel' gain control, recessed to avoid accidental rotation, may be used to adapt the audio levels to different devices such as Fatshark goggles.


  • GPS, Battery, RSSI, Altitude and more is viewable
  • Compatibility with iPhone/iPad (android currently not supported)
  • Integrated gain control for greater TX/RX compatibility
  • Headphone output jack, for in-flight audio feedback
  • No battery/power required
  • Standard 3.5mm jack input and outputs


  • Iphone/Ipad
  • To take full advantage Ezuhf is recommended
