Pololu 1365 / 1364 High-Power Simple Motor Controller G2 - 24v12
The Pololu 1365 / 1364 High-Power Simple Motor Controller G2 is a compact, versatile DC motor speed and direction controller designed for high-current applications up to 12A at 24V, making it ideal for robotics, industrial automation, and mobile platform development. Professional engineers and roboticists rely on this controller for precise motor management in autonomous systems, drone platforms, and heavy-duty machinery where reliable PWM-based speed control and bidirectional operation are critical. This controller solves the challenge of managing high-power DC motors with minimal complexity while providing robust protection against voltage spikes, overcurrent conditions, and thermal issues that can damage sensitive microcontroller pins.
Product Overview
The Pololu High-Power Simple Motor Controller G2 operates on the principle of pulse-width modulation (PWM) to regulate motor speed and direction independently. The device accepts logic-level signals from microcontrollers like Arduino, Raspberry Pi, or STM32 boards and converts them into high-current motor drive signals using integrated MOSFET H-bridge architecture. The 24V12 variant is specifically engineered to handle continuous currents up to 12 amperes at 24 volts, with peak current handling capabilities exceeding 15A for short durations, making it suitable for demanding applications such as electric wheelchairs, autonomous ground vehicles, and industrial conveyor systems.
What distinguishes this G2 generation controller is its advanced protection circuitry including thermal shutdown at 160 degrees Celsius, configurable current limiting via analog feedback sensing, and integrated reverse-polarity protection that safeguards against accidental wiring errors. The controller features a simple three-pin interface for speed control and direction selection, eliminating the need for complex PWM frequency calculations on the host microcontroller. Its compact form factor and integrated heat dissipation design allow mounting directly on robot chassis or industrial control panels without requiring external cooling solutions for most continuous-duty applications.

How to Use
To implement the Pololu 1365 / 1364 controller, first verify your power supply voltage is within the 5.5V to 30V range and can supply at least 12A continuous current for your motor load. Connect the motor power supply positive terminal to the VIN pin and negative to GND, then connect your DC motor leads to the OUT1 and OUT2 terminals. The controller accepts three control signals from your microcontroller: the PWM speed control pin accepts 0-5V logic signals where frequency should be between 5kHz and 20kHz for optimal performance, the direction pin determines motor rotation polarity, and the enable pin allows software-controlled shutdown. Configure your microcontroller to generate appropriate PWM signals, starting with 50 percent duty cycle for testing, then gradually increase speed while monitoring current draw and controller temperature to ensure operation remains within safe limits.
For robust system design, always include a large electrolytic capacitor (minimum 470uF at 35V) across the motor power supply terminals to suppress voltage spikes during motor commutation and direction reversals. If your application requires smooth acceleration ramping, implement software PWM duty cycle gradients on your microcontroller rather than abrupt speed changes, which reduces mechanical stress and electrical noise. In high-noise industrial environments, add a 0.1uF ceramic capacitor directly across the PWM input signal pins to filter out electromagnetic interference. For maximum reliability, monitor the controller's thermal output and ensure adequate airflow around the device if operating continuously at currents above 10A.
Frequently Asked Questions
Can the Pololu 1365 / 1364 controller handle motors rated for different voltages?
The controller operates across 5.5V to 30V, so it can drive motors rated anywhere within this range. However, always match your power supply voltage to your motor's rated voltage for optimal performance and motor lifespan. Running a 12V motor at 24V will significantly reduce motor life due to increased heat generation and winding stress. The controller itself handles the voltage difference safely, but the motor may suffer damage.
What is the maximum PWM frequency I should use with this controller?
The Pololu G2 controller is optimized for PWM frequencies between 5kHz and 20kHz. Frequencies below 5kHz may cause audible motor noise and reduced smoothness, while frequencies above 20kHz can increase switching losses and heat generation in the MOSFETs. Most Arduino boards default to 490Hz PWM, so you will need to reprogram the timer registers to achieve the recommended frequency range for best performance.
How do I protect the controller from back-EMF spikes when the motor suddenly stops or reverses direction?
The controller includes integrated freewheeling diodes that handle back-EMF from motor deceleration. However, for additional protection in harsh environments, add a 470uF to 1000uF electrolytic capacitor across the power supply terminals and consider adding a transient voltage suppressor (TVS) diode rated for your maximum voltage across VIN and GND. These components work together to clamp voltage spikes below safe levels and protect the MOSFET gates from overstress.
