Getting Started – Victor SPX
The Victor SPX is a speed controller designed through collaboration between VEX Robotics
(vexrobotics.com) & Cross the Road Electronics (ctr-electronics.com) that allows for fine control and high
performance of brushed DC motors in competition robotics applications. The Victor SPX 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 all FRC motor applications from drivetrains to shooter
wheels.
The plastic housing and aluminum heatsink create a lightweight motor controller – while maintaining
the full sealed, fan-less design that FRC teams expect. This, combined with a 3 sq-in. footprint, a variety of
built-in mounting options and super flexible, high strand count leads make installation a breeze.
