5. Setup
Follow these steps to properly set up your TB6612FNG motor driver module.
5.1 Pinout and Connections
The module features several pins for power, control signals, and motor outputs. Ensure all connections are secure and correctly oriented.
Figure 3: Pin layout of the TB6612FNG module.
5.2 Power Supply Connection
Connect your power supply to the designated VCC and GND pins. The module typically operates within a voltage range suitable for common microcontrollers and motors. Refer to the TB6612FNG datasheet for precise voltage limits. An external power supply filter capacitor may be required for stable operation, especially with noisy motors.
5.3 Motor Connection
Connect your DC motors or 4-wire stepper motor to the output terminals. The module provides two independent motor channels (A and B).
- For DC Motors: Connect one DC motor to the MA1/MA2 pins and another to the MB1/MB2 pins. Polarity determines direction.
- For Stepper Motors: Connect a 4-wire stepper motor by pairing its coils to MA1/MA2 and MB1/MB2. Consult your stepper motor's datasheet for coil identification.

6. Operating Instructions
Once the module is correctly wired, you can begin controlling your motors.
6.1 Driving DC Motors
To control a DC motor, you will typically use two input pins per motor (e.g., INA1, INA2 for Motor A) and a PWM signal for speed control. By setting the logic levels on INA1 and INA2, you can control the direction of the motor. A PWM signal applied to the PWMA pin controls the speed.
- Forward: INA1 = HIGH, INA2 = LOW
- Reverse: INA1 = LOW, INA2 = HIGH
- Brake: INA1 = HIGH, INA2 = HIGH (or LOW, LOW depending on implementation)
- Stop (Coast): INA1 = LOW, INA2 = LOW
6.2 Driving Stepper Motors
For stepper motors, the module can be used in full-step, half-step, or micro-stepping modes depending on the control signals provided by your microcontroller. This typically involves sequencing the logic levels on the INA1, INA2, INB1, and INB2 pins. Consult a stepper motor control guide for specific sequencing patterns.
6.3 Sleep Mode
The TB6612FNG features a low power sleep mode. To activate sleep mode, pull the STBY pin LOW. This disables the motor outputs and reduces current consumption. To wake the module, pull the STBY pin HIGH.
7. Maintenance
The TB6612FNG module is designed for durability and requires minimal maintenance.
- Cleaning: Keep the module free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid liquid cleaners.
- Storage: Store the module in a dry, static-free environment when not in use.
- Inspection: Periodically inspect connections for looseness or corrosion. Check for any visible damage to the PCB or components.
8. Troubleshooting
If you encounter issues with your TB6612FNG module, refer to the following table for common problems and potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor not moving | No power, incorrect wiring, STBY pin LOW, incorrect control signals | Verify power supply, check all connections, ensure STBY is HIGH, review control logic. |
| Motor moves erratically | Insufficient power, loose connections, noisy signals, motor overload | Check power supply capacity, secure connections, ensure clean control signals, reduce motor load. |
| Module overheating | Excessive motor current, prolonged high load, insufficient ventilation | Ensure motor current is within limits, reduce load, provide adequate airflow around the module. |
| Motor makes noise but doesn't turn (stepper) | Incorrect stepper sequence, insufficient current, motor stalled | Review stepper control sequence, verify power supply, check for mechanical obstructions. |
