TB6612FNG Ultra Small Dual DC Motor Driver Module

The TB6612FNG Ultra Small Motor Driver Module is a highly efficient, dual H-bridge motor driver designed to deliver performance comparable to the classic L298N, but in a fraction of the size. Utilizing MOSFET outputs instead of bipolar transistors, it significantly reduces voltage drop and heat generation, making it vastly more efficient. Capable of driving two DC motors or one stepper motor, this ultra-compact module is the perfect drop-in alternative for robotics, smart cars, and portable DIY electronics where space and power efficiency are critical.

Key Features

• Ultra-small form factor compared to bulky L298N modules
• Dual H-bridge: drives two DC motors or one stepper motor
• MOSFET-based output for higher efficiency and lower heat dissipation
• Built-in thermal shutdown and overcurrent protection
• Compatible with 3.3V and 5V logic levels (Arduino, ESP32, Raspberry Pi)
• Lower voltage drop than traditional L298N drivers
• Includes standby (EN) pin for instant motor halt

Technical Specifications

Applications

• Robotics and autonomous smart cars
• Compact DIY electronics replacing L298N drivers
• Battery-powered portable motor projects
• Stepper motor control
• IoT devices requiring small footprint actuation

Important Notes

• Ensure the VM (Motor voltage) and VCC (Logic voltage) are correctly connected; do not exceed their maximum ratings.
• The standby (STBY) pin must be pulled HIGH for the motors to operate; if left floating, the driver will remain disabled.
• Requires PWM pins on your microcontroller to control the speed of the motors.
• While highly efficient, ensure adequate ventilation if running motors at the maximum continuous current limit.
• Always disconnect power before wiring or changing motor connections to prevent short circuits.
