DFRduino L298N Dual Channel DC Motor Driver Shield

SKU: DRI0009

The DFRduino L298N Dual Channel DC Motor Driver Shield for DFRduino is designed to drive two DC motors using the L298N chip, delivering up to 2A per channel. Speed control is achieved via PWM from DFRduino's Pins 5 and 6, while motor enable/disable is signaled through Pins 4 and 7. The shield can be powered directly from DFRduino or an external source, with external power supply recommended for optimal performance.

    Control Mode Selection JumpersControl Mode Selection Jumpers

    The shield supports PWM and PLL(Phased Locked Loop) control Modes. The PWM mode uses E1 and E2 to generate PWM signal. The PLL mode uses M1 and M2 to generate phase control signal.

    Motor Terminal

    Two DC motors are connected to blue motor terminals. The male header behide the terminals are the same as the motor terminals.

    Arduino_Shield5

    PWRIN

    The motors can be powered by external power supply when the motor current exceeds the limits provided from the Arduino. The swith between external and Arduino power is implemented by two jumpers.

    PWRIN: External Power
    VIN: Arduino Power

    Arduino_Shield6

    When the motor shield is powered by external power source, make sure the external power source and Arduino have the same GND.
