The jrk 12v12 motor controller is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage, and hobby radio control (RC). For the 4m boat, the Arduino and Pololu will communicate using serial interface. The controller can be used as an open-loop speed control or for closed-loop speed or position control. This motor controller will be used by the team for the first time in the 2012-2013 year.

User Manual:

Compatible Operating Systems and Configuration:

  • The jrk must be initially configured from Windows
  • After configuration, the jrk can be used with Microsoft Windows 7, Windows Vista, Windows XP, Linux, and Max OS X 10.7 or later
  • During configuration, settings such as input, motor, feedback, PID, and error response options can be set


  • 6 V to 16 V operating supply range
  • 12 A maximum continuous current output (30 A peak)
  • Has reversed power protection


  • Duty cycle of -600 to 600 (where 600 is full forward and -600 is full reverse)
  • The jrk is capable of both 20kHz and kHz PWM (higher frequency means greater power loss)

Serial Communication:

  • Available baud rates: 300-11 520 bps (can be pre-set or auto-detected)
  • Communicates using TTL non-inverted serial signals on TX and RX lines
  • See the user manual for more information about command protocols
