Background[]
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.

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