Spark Motor Controller

The REV Robotics Spark Motor Controller is an inexpensive brushed DC motor controller designed to give FIRST® Robotics Competition teams more bang for their buck.

The Spark features 60A continuous current with passive cooling, bi-directional limit switch inputs for smart mechanism control, an RGB LED status indicator,  and a button-activated brake/coast mode.


  • Passive cooling
    • No fans required
  • Synchronous rectification
    • Reduces heat generation
  • Limit switch inputs
    • Stops forward and/or reverse motion automatically
    • No programming required
    • Compatible with normally open (NO) limit switches
  • Calibration
    • Factory calibrated to 1ms – 2ms input signal
    • User calibratable
  • Integrated cable retention for PWM port
  • Clamping screw terminals
    • Better contact area and retention
  • RGB status LED
    • Detailed mode and operation feedback

Output Linearity

The following data was taken with a free spinning CIM motor and a 12V power source. The flat zone in the middle represents the 40μs input deadband around the neutral pulse width.

Temperature performance

The following data was taken with a constant 12V power source and 40amp load. Temperatures were measured with thermocouples located in 4 locations (on the mosfets, on the capacitors, ontop of the heat sink, and on outside of the plastic housing.
