  • You need 4 PWM pins

    posted by ebludt

    It´s cheap. Works. A l298H driver. You can control 2 dc motors.Es barato y funciona. Puedes controlar 2 motores DC.
    4 PWM!!! you need 3 pins for motor.Enable.Pwm CWpwm CCW.Yo need 2 pwm for each motor.Usa 4 PWM pines. Demasiados.Enable.PWM CWPWM CCWSi vas mal de pines PWM busca otro producto.
    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.
  • Works as expected, and at a very affordable price

    It was cheap, less than the price for a L298 chip alone in my country.I had no problem hooking it up to a stepper motor, and the onboard 5V supply regulator comes in handy for supplying other parts of my project.Each output as a green led associated with it so you can verify the stepping sequence,It also have a switch that can be used to shut off the controller board.
    I'm using this board connected to a parallell port. Hook a common ground to the GND part of the power terminal, then signal the IN pins in correct order to step the motor.
    Useful, cheap, and of acceptable build quality. I will be buying more of these because it was so easy to use.
  • Small, cheap and good quallity

    Great price. Small as i expected. Good quallity at this price.
    If you make an analogy between L298 and L9110, L9110 can see that the does not have enable/disable pin.In other words is simply connected to the Arduino, in my case.External power supply must be used to avoid power problems.
    Connect with an Arduino Mega (bought from DX) works very fine with 2 micromotors.
