Compatibility and Use Cases

• Arduino and compatible microcontrollers for robotics and motion control
• Raspberry Pi projects that require motor actuation via GPIO and PWM
• Educational projects, prototypes, small CNC axes, camera sliders, and mobile robots

Wiring Guide and Typical Connections

Basic wiring is straightforward. Keep logic and motor power supplies separate if they use different voltages.

• VM (motor power): Connect to motor supply (2.5V to 13.5V). Add a decoupling capacitor close to the board.
• VCC (logic power): Connect to 3.3V or 5V logic depending on your controller.
• GND: Common ground between controller and motor power.
• AIN1 / AIN2 and BIN1 / BIN2: Direction control inputs for motor A and B.
• PWMA / PWMB: PWM speed control inputs for motor A and B. Use microcontroller PWM pins for speed regulation.
• STBY: Pull HIGH to enable the driver. Pull LOW to disable and reduce standby current.
• Motor outputs: AO1/AO2 and BO1/BO2 connect to motor coils or motor terminals.

Stepper Motor Notes

To drive a bipolar stepper motor, use both H-bridges as separate phase drivers and sequence AIN1/AIN2 and BIN1/BIN2 with appropriate PWM for current control. The TB6612FNG is ideal for full-step and half-step driving, but it does not provide advanced current microstepping on its own. For fine microstepping, use an external stepper controller with current regulation.

Example Arduino Wiring (Summary)

• VCC to 5V on Arduino
• VM to motor battery or power supply (add decoupling capacitor)
• GND to Arduino GND
• PWMA to Arduino PWM pin (e.g., D5), AIN1/AIN2 to two digital pins for direction
• PWMB to another PWM pin, BIN1/BIN2 to digital pins for second motor
• STBY tied HIGH to enable or controlled by a digital pin
