dc motor driver Customers Reviews

  • Small, cheap and good quallity

    posted by korlenn

    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.
  • l298 good h bridge

    posted by eduaugal

    es un buen producto tomando en cunta la relacion costo calidad, es relativamente facil de usar, permite al usuario conectar el dispositivo L298 directamente a un motor de corriente directa y controlarlo mediante un pulso TTL, practicamente realiza toda la etapa de amplificacion y potencia en una sola tarjeta, sin mencionar que tambien incluye los diodos de proteccion para sobrecorriente y corto circuito
    tiene una buena disipacion de calor y tiene un buen tamaño para ser incluido en un proyecto de robotica.
    es un producto recomendable y de buena calidad
  • Very fast motors

    posted by ffusarouba

    Cheap and fast motors. Works as expected. One tested for spin gave more than 33000 RPM at 6V and more than 52000 RPM at 12V.
    I´m going to use them in slot cars but I believe that the 12V system will burn them soon. I tested them at this voltage and they start to heat, as expected
    As they are cheap I feel no sorry of them on the experiments. The projected ones for 12V spin 18000 to 21000 RPM, so one can just pull controller half way to not burn them, having same spin.
  • Great circuit for controlling two DC-motors or stepper motor

    posted by SamiVakkuri

    Great circuit for controlling two DC-motors (or stepper motor). I use it with 12V battery and Arduino Mega to control ~20W motor and it works properly.
    Here example about working: A1: A2: Motor state:| 0 | 0 | Freerun| 1 | 0 | Clockwise| 0 | 1 | Counter-Clockwise| 1 | 1 | Brake (motor short circuit)-You can control speed of motor with PWM-signal
    Great and cheap for anyting with quite powerful DC-motors.
  • Awesome, I am very satisfyed

    posted by duodecimo

    The products (I have bought 2 motors) where very carefully packed, and this is awesome. The motors worked out of the box, no problem (other that I had to find a schema to connect things in the internet).
    It would be great if there were instructions on how to connect the product with the Arduino board, along with some example code.
    In the end, after finding a schema of connection and a sample code on the web, all worked as expected. The motors are slow, but very strong, and my circuits did not heat at all. I was very pleased with my purchase.
