Jaguar Motor Controller


The Jaguar Motor Controller provides variable speed control for both 12 V and 24 V brushed DC motors at up to 40 A continuous current. Includes a rich set of sensor interfaces, connectivity, and control options, including analog and quadrature encoder interfaces, high-performance Controller Area Network (CAN) interfaces, and an RS232 port.

  • Quiet control of brushed DC motors.
  • High current capacity with low voltage drop.
  • Color-coded screw terminals for all power wiring.

Engineered, assembled and tested in the USA.

Discontinued. We recommend the Talon SRX as a replacement option. See the VEX Robotics & Cross the Road Announcement for more information.


Availability: Discontinued



Current Draw

The Jaguar Motor Controller includes a software current limit. This current limit protects the Jaguar hardware from damage. This limit is based on 3 current draw values in the firmware; a value at which the controller will never shut off, a value at which the controller will shut off after a short period of time, and a value at which the Jaguar will immediately shut off. After experimentation, the immediate shut-off ceiling was raised in the v107 firmware to better reflect the capabilities of the Jaguar hardware, and to better perform in FIRST ® Robotics Competition applications (when the Jaguar is protected by an external circuit breaker).
