The Pololu Dual G2 High-Power Motor Driver 18v18 Shield uses pairs of discrete MOSFET H-bridges to drive two large brushed DC motors. It has an Arduino shield form factor for direct plug-in use, and also breaks out all motor driver pins along the left side for standalone operation without an Arduino.
This 18v18 version operates from 6.5–30 V and delivers up to 18 A continuous per channel (with appropriate heatsinking and airflow), making it suitable for driving high-power motors in robotics and automation projects.
Key Features
- Dual H-Bridge – Drive two brushed DC motors independently
- Discrete MOSFET Design – High-power capability with low on-resistance
- Arduino Shield Form Factor – Plugs directly into Arduino Uno, Mega, and compatible boards
- Standalone Mode – All motor driver pins broken out for use without Arduino
- Current Sense – Analogue current sense output for each motor
- PWM Speed Control – Direction and speed control via digital pins
Specifications
- Motor Channels: 2
- Operating Voltage: 6.5–30 V
- Continuous Current: Up to 18 A per channel (with heatsinking)
- Logic Voltage: 5 V (from Arduino)
- Driver Type: Discrete MOSFET H-bridge
- Form Factor: Arduino shield
Ideal For
- High-power robotics platforms
- Dual-motor drive systems
- Arduino-based motor control projects
- Standalone motor driver applications

Jargon buster
Plain-language definitions for the technical terms used above.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
