Product Description

The TB6612FNG Module is engineered for precision motion control. Unlike Bipolar-junction transistor drivers that drop significant voltage (wasted as heat), the MOSFETs in this chip have a very low ON-resistance, ensuring that almost all your battery power reaches the motors. The module features a dedicated Standby (STBY) pin, which can be pulled low to put the driver into a deep-sleep mode, drastically extending battery life for IoT and mobile robotics projects. Its breadboard-friendly header layout makes it easy to integrate with Arduino, ESP32, or STM32 microcontrollers.

Key Features

  • Dual Channel Control: Independently control the speed and direction of two DC motors.

  • Ultra-Compact Volume: Occupies a fraction of the space required by an L298N module, perfect for palm-sized robots.

  • PWM Speed Control: Supports PWM frequencies up to 100 kHz, allowing for silent and smooth motor operation.

  • Low Power Standby: Integrated power-saving mode reduces current consumption to nearly zero when the robot is idle.

  • Safe Operation: Includes internal filtering capacitors and protection diodes to handle back-EMF from the motors.

Technical Details

  • Logic Compatibility: Works seamlessly with both 3.3V and 5V logic controllers.

  • Thermal Performance: Operates coolly at 1A; no bulky heat sink required for standard hobby motors.

  • Mounting: Standard 0.1" (2.54mm) pitch headers.

Prototyping and Engineering Tips from Robogears

  • The STBY Pin Requirement: One of the most common "mistakes" is forgetting to connect the STBY pin. By default, it must be pulled HIGH (to VCC) for the driver to function. If you leave it disconnected, your motors will not move, even if your code is perfect.

  • Power Sequencing: Always connect your Logic VCC (2.7V-5.5V) and Motor VM (up to 13.5V) separately. While they can share a ground, keeping the logic power stable prevents the microcontroller from resetting when the motors pull a heavy "stall" current.

  • Decoupling is Essential: Although the module has small onboard caps, we recommend adding a 100uF electrolytic capacitor across the VM and GND pins if you are using high-torque motors. This prevents voltage ripples from interfering with your sensors or MCU.

  • L298N Comparison: If you are switching from an L298N, you will notice your robot moves faster at the same PWM duty cycle. This is because the TB6612FNG has a much lower voltage drop (approx. 0.5V vs 2.0V+ on the L298N). You may need to recalibrate your PID loops or speed settings.

Package Includes

  • 1 x TB6612FNG Dual DC Motor Driver Module

  • 2 x Male Header Strips (Unsoldered)

Disclaimer

Do not exceed the 13.5V motor voltage limit. Ensure the peak current does not exceed 3.2A for more than a few milliseconds to avoid permanent damage to the MOSFET gates.
