    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:

    It´s cheap. Works. A l298H driver. You can control 2 dc motors.
    Es barato y funciona. Puedes controlar 2 motores DC.

    Cons:

    No manual or datasheet. You need google and time.
    No hay manual ni datasheet. Necesitas bastante tiempo tirando de google.

    OtherThoughts:

    4 PWM!!! you need 3 pins for motor.
    Enable.
    Pwm CW
    pwm CCW.

    Yo need 2 pwm for each motor.

    Usa 4 PWM pines. Demasiados.
    Enable.
    PWM CW
    PWM CCW

    Si vas mal de pines PWM busca otro producto.

    Bottomline:

    A lot of PWM pins used. You ned 6 PWM if you want PWM controls of motors. 2 digital PINS more.

    Othe H bridge use 4 digital PIN and only 2 PWM pins.
