Talon SRX – User’s Guide
The Talon SRX is a speed controller designed through collaboration between VEX Robotics
(VEX.com) & Cross the Road Electronics (crosstheroadelectronics.com) that allows fine control and
high performance of brushed DC motors in competition robotics applications. The Talon SRX handles
high current loads with minimal voltage drop and heat generation. Its linear output and Brake/Coast
options allow for precise motor control, making it well suited for everything from drivetrains to shooter
wheels.
The Talon SRX’s Data Port and CAN bus features make it the most capable motor controller
available for competition robotics. The Data Port allows Quadrature Encoders, Limit Switches and
Analog Sensors to be connected directly to the motor controller. Sensors that are connected through
the Data Port are directly processed by the Talon SRX, freeing up resources in the primary robot
controller for more complex user code. When using CAN bus, up to 63 Talon SRXs can communicate
with the primary robot controller for tasks like field-upgrade, Data Port Configuration, dynamic
Brake/Coast toggling, and motor control.
The lightweight aluminum case was designed using extensive Finite Element Heat Transfer Analysis
(FEHTA). The result is a fully sealed design that makes fans optional. This, combined with a 3.25 sq.
in footprint, a variety of built-in mounting options, and super-flexible/high-strand-count leads, makes
installation a breeze.
