  • Motor channels: 1
  • Maximum PWM frequency: 20 kHz
  • Operating voltage: 5.5 V - 24 V
  • Continuous output current per channel: 12 A
  • Motor driver: VNH5019

The Pololu 12A, 5.5 - 24V Single Motor Controller operates from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak). It works with 2.5 to 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current sense feedback (an analog voltage proportional to the motor current). Along with built-in protection against reverse-voltage, over-voltage, under-voltage, over-temperature, and over-current, these features make this product a great general-purpose motor driver. It includes a 47 uF electrolytic power capacitor, and there is room to add additional capacitors.

We use these for the 4 person team Skills Ontario Robotics competition for the last 2 years to control all parts of our robots they work awesome!

Good value

Super-prompt service and a fair price from Robotshop. Robust and well documented. Doesn't break a sweat running at 4.7A 19V. Nice that they include the connection terminals. One strange quirk: The current sense output is a bit asymmetric and there is a small deadband around zero -- so positive and negative currents require different zero offset calibration constants.

Works fantastic!!

They motor controllers are very easy to interface with and are very reliable. We were using them for two motor that drew 8A continuous and 13A peak for short durations. These controllers did not heat up or get damaged.
