The Talon SRX offers the latest in smart speed controller technology compressed into a robust, compact package. This latest iteration of the popular Talon platform from Cross the Road Electronics adds support for CAN, additional communication protocols, and integrated PID control.
The Talon SRX has the following new features...
- Two new sensor types for CTRE Magnetic Encoder (absolute and relative).
- Voltage Compensation Mode. Motor Output is expressed in output volts, and Talon will modulate the output based on battery voltage measurement.
- Current Closed-Loop Mode. Talon will servo to a target current-draw.
- User can now select the nominal forward and reverse output during Closed-Loop. This means that if the Closed Loop Error is nonzero (or outside of the Allowable Closed-Loop Error) but the Closed-Loop calculates a motor output that is weaker than the specified nominal value, Talon will promote the motor output to the nominal value.
- Use can now specify the peak forward and reverse output during Closed-Loop.
- User can now select the Allowable Closed-Loop error so that the motor drive remains neutral even if closed-loop error is nonzero.
- Talon supports an advanced control mode called Motion Profile, that allows streaming the trajectory points of a motion profile into a Talon, while the Talon executes it. This ensures accurate timing between trajectory points.
- Robot API supports unit scaling so sensor position/velocity and Closed-loop target position and velocity can be expressed in rotations and RPM. roboRIO Web-based config also will decode in rotations and RPM.
The Talon SRX was co-developed through a collaborative partnership between VEX Robotics and Cross the Road Electronics. Click here to learn more about this exciting partnership.

In addition to support for CAN and other advanced communication protocols, the Talon SRX includes a compilation of smaller features that add up to a robust all-inclusive motor speed controller.
- CAN and Digital IO protocols augment motor speed control with direct sensor feedback
- Onboard closed-loop PID control algorithms make complex motor control accessible to all teams
- Full aluminum case, passive cooling fins, and sophisticated internal components make fans optional
- Completely sealed enclosure prevents debris from getting anywhere it shouldn't be
- Electrically insulated components allow for direct controller mounting to a robot frame with no fear of shorting
- LED indicators blink proportionately to output speed for easier debugging
- Illuminated "Brake / Coast Calibration" button enables one-touch setting changes and calibration
- Robust embedded power & output cables will never shake loose during a match
- Built-in pockets sized for #8 nuts and zip tie grooves make rigid mounting simpler than ever
- Integrated sign-magnitude synchronous rectification reduces heat generation at full motor stall
- 15.625 kHz output switching frequency ensures smooth and precise motor control
- Plug and play support for the CTRE Magnetic Encoder Sensor making sensor feedback even easier
