Description
The Motor Driver TB6612FNG Module can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes – CW, CCW, short-brake, and stop.
The two motor outputs (A and B) can be separately controlled, and the speed of each motor is managed via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Logic supply voltage (VCC) can range from 2.7V to 5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC.
The board comes fully assembled with decoupling capacitors installed on both supply lines for clean power filtering. All pins of the TB6612FNG are neatly broken out to standard 0.1″ pitch headers, arranged logically with input pins on one side and output pins on the other.
Key Features
- Output Current Rating: Delivers an average continuous current of 1.2A with a 3.2A peak pulse capacity per channel.
- Power-Saving Standby Mode: Dedicated STBY control pin to drop power consumption when motors are inactive.
- Versatile Control Modes: Supports Clockwise (CW), Counter-Clockwise (CCW), short-brake, and stop motor operation modes.
- Built-In Safety Protections: Features an integrated thermal shutdown circuit and a low-voltage detecting circuit to prevent hardware burnout.
- Clean Power Filtering: Includes filtering decoupling capacitors on both supply lines for noise reduction.
- Breadboard Friendly: All pins broken out to standard 0.1″ spaced headers for easy wiring and prototyping.
Benefits
- High Efficiency & Low Heat: MOSFET-based H-bridge architecture generates significantly less heat compared to older driver ICs like the L298N.
- Precise High-Frequency Control: Supports up to 100kHz PWM frequency input, ensuring ultra-smooth speed control transitions.
- Compact Form Factor: Small physical footprint (30 x 20 x 10 mm) makes it ideal for space-constrained mobile robotics.
Applications
- Miniature Mobile Robotics: Ideal motor driver for two-wheel drive (2WD) line-following robots, obstacle-avoiding rovers, and small automated guided carts.
- Smart Camera Sliders & Pan-Tilt Mounts: Smooth, low-noise DC motor control for lightweight camera motion control rigs and automated photography sliders.
- Small Automation & Prototyping: Perfect for driving miniature conveyor belts, sorting mechanisms, and custom mechanical actuators in DIY maker projects.
- Precision Laboratory Stirrers & Dispensers: Low-power rotational control for compact mixing apparatus, sample trays, and miniature fluid pump systems.
