Quad DC Motor Driver Shield for Arduino DFRobot Quad DC Motor Driver Shield for Arduino is a quad motor driver shield for Arduino. The DFRobot shield is compatible with the 5V/3.3V Arduino controller and can control up to four DC motors with 8 pins simultaneously. The device supports PWM speed control and polarity control. The driver shield includes two TB6612FNG motor driver chips, compared with the traditional L298N chip. This improves efficiency and reduces the component size. The module includes a built-in low voltage detection circuit and thermal shutdown protection circuit.
