Pololu 3284 / 3285 / 3286 / 2398 / 3287 / 3292 / 3583 / 3582 RoboClaw Motor Controller - 2 Channel
The RoboClaw Motor Controller is a sophisticated dual-channel brushed DC motor controller designed for robotics, autonomous vehicles, and industrial automation applications requiring independent motor speed and direction control. Professional roboticists, autonomous platform developers, and embedded systems engineers rely on this controller to manage high-current motor loads with precision PWM control and real-time feedback monitoring. This product solves the critical challenge of independently controlling two DC motors with simultaneous acceleration ramping, current limiting, and encoder-based velocity feedback in space-constrained robotic platforms.
Product Overview
The RoboClaw Motor Controller operates as a microcontroller-based motor driver that accepts serial, USB, or analog input commands to regulate two independent brushed DC motors. The device employs advanced H-bridge topology with integrated MOSFETs capable of delivering continuous current up to 30A per channel, with peak current handling of 60A, making it suitable for high-torque robotic actuators. The controller features built-in encoder interface support for closed-loop velocity control, allowing real-time speed regulation and position tracking essential for wheeled robots, robotic arms, and autonomous navigation systems.
This motor controller distinguishes itself through its multi-protocol communication interface supporting serial UART, USB, and analog voltage inputs simultaneously, enabling seamless integration with microcontrollers, single-board computers, and legacy control systems. The firmware includes sophisticated motion profiling capabilities with configurable acceleration/deceleration ramps, current limiting thresholds, and temperature monitoring to prevent thermal damage. Advanced features such as quadrature encoder reading, PID velocity control loops, and motor stall detection make this controller ideal for precision applications requiring responsive motor management and diagnostic feedback.

How to Use
Begin by connecting your power supply to the RoboClaw controller, ensuring the voltage falls within the 6V to 34V DC specification range. Connect your two brushed DC motors to the M1 and M2 output terminals, observing correct polarity for forward rotation direction. For encoder feedback, attach your quadrature encoder signals to the encoder input pins on the controller, configuring encoder counts per revolution in the firmware settings using the Pololu Configuration Utility software.
Establish communication with your microcontroller or single-board computer using your preferred protocol: serial UART for direct microcontroller integration, USB for computer-based control systems, or analog voltage input for simple potentiometer-based speed control. Load your control firmware onto your host microcontroller using the Pololu motor control library, setting acceleration ramps, current limits, and PID gains appropriate for your motor specifications and load characteristics. Test motor response through the Configuration Utility before deploying to your robotic platform, verifying encoder readings and current draw under typical operating loads.
Frequently Asked Questions
What is the maximum voltage and current this motor controller can handle safely?
The RoboClaw controller accepts input voltages from 6V to 34V DC, with continuous current ratings of 30A per channel and peak current handling of 60A per channel. These specifications accommodate most brushed DC motors used in robotics, from small 12V hobby motors to larger 24V industrial actuators. Always verify your motor's current draw under load does not exceed these limits, and ensure adequate heat dissipation through proper mounting and ventilation.
How do I configure the PID velocity control loop for my specific motors?
Use the Pololu Configuration Utility to adjust the proportional, integral, and derivative gains for each motor channel independently. Start with conservative P values around 32, I values around 16, and D values around 4, then incrementally increase P gain while monitoring for oscillation. Test your configuration with actual encoder feedback under typical load conditions, adjusting gains until the motor achieves target velocity within 100ms without overshooting or oscillating.
Can I use this controller with brushless DC motors or stepper motors?
The RoboClaw is specifically designed for brushed DC motors and cannot directly drive brushless motors or stepper motors without additional external drivers. For brushless motor control, consider Pololu's brushless motor controllers designed for three-phase commutation. Stepper motors require dedicated stepper drivers with microstepping capability, which this controller does not provide.
