Pololu Jrk 12A 6-16V USB Motor Controller with Feedback

• Brushed DC motor controller
• Supports four interface modes
• Operating voltage: 6-16V
• Continuous output current: 12A

The Pololu Jrk 12A 6-16V USB Motor Controller with Feedback is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog voltage and hobby radio control (RC). The controller can be used as an open-loop speed control or for closed-loop speed or position control. The continuous output current is approximately 12A (30A max) and the operating range of 6-16V with transient protection up to 40V. The analog voltage and tachometer (frequency) feedback options allow quick implementation of closed-loop servo systems, and a free configuration utility (for Windows 7, Vista, or Windows XP) allows easy calibration and configuration through the USB port.

Key improvements over competing products and earlier Pololu motor controllers with feedback include:

• USB connectivity with emulated serial (COM) port allows direct motor control from a PC.
• Ultrasonic PWM to eliminate switching-induced motor shaft hum or whine.
• Robust, high-speed communication protocol with user-configurable error condition response.
• High internal resolution (12 bits) for smooth and flexible calibration to various input and feedback devices.
• Current sensing and limiting.
• Reversed power protection.
• Field-upgradeable firmware.

For more main features please see JRK motor controller's user's guide in useful link tab. The Pololu Jrk 12A 6-16V USB Motor Controller comes with a 14×1 straight 0.100" male header strip and two 5mm, 2-pin terminal blocks. To provide maximum flexibility, none of these parts are soldered to the board. For the most compact installation, you can solder wires directly to the jrk pads themselves and skip using the included hardware. The included hardware allows you to make less permanent connections. You can break the 14×1 header strip into an 8×1 piece and two 3×1 pieces and solder these strips into the jrk's I/O pads.

Note: The USB cable is not included.
