Traxxas changed the game with Telemetry allowing you to monitor and record real-time data from your vehicle. By combining the water-sealed Telemetry Expander with the GPS Module, Traxxas gives you the ability to accurately track real-time speed! The Telemetry Expander allows you to support up to six plug-and-play "smart" sensors in addition to the three standard Traxxas sensors. There are currently three different smart sensors to select from; voltage, temperature, and GPS. The smart sensor advantage is that the Traxxas Link application automatically recognizes the sensors, so setup only takes a few moments! Install the Telemetry Expander, plug in the sensors and communication cable and prepare for Telemetry like you've never seen!

Telemetry Expander
With the revolutionary Traxxas TQi radio system, Traxxas Wireless Link Module, and the Traxxas Link app (available free from Google Play or the Apple App Store), your Apple iPhone® (4S, 5, 5C, 5S), iPod Touch® (5th generation and later versions), iPad® (3rd generation and later versions), iPad Mini®, or Android® 4.4 equipped device, can be transformed into a powerful tuning tool that allows you to replace the transmitter's button/LED programming system with an intuitive, high-definition, full-color graphical user interface. You can make changes to radio trims and settings, input vehicle profiles, update model memory, and adjust setups for different driving conditions by means of a virtual dashboard and interactive screens. Using the complete TQi system and impressive Traxxas Link app makes pro-level transmitter tuning fast, convenient, and easy.

Once the telemetry-ready accessories and sensors are installed, information can be viewed by selecting the dashboard from the Traxxas Link app's home screen. The application automatically detects and recognizes the installed telemetry sensors for easy setup and the Traxxas Link dashboard comes to life! All displayed data can be recorded and saved for easy play-back later so you can share it with friends and other RC enthusiasts (and so you can keep your eyes on the vehicle as you drive!).

With the Telemetry Expander, including a powerful communication cable and a series of plug-and-play sensors, installation and operation of the telemetry system using Traxxas Link becomes almost effortless.
