    Built-in microphone and speaker quality rather loud.six sounds more than enough, and even some special signals like ambulances and police. Built-in microphone is pretty good passes all say ...In traffic and when you need to rush ahead of the car riding an indispensable thing.
    generally satisfied with the purchase, the truth may be at odds with the police))
    Must have!!
  • good product

    This is a very nice little L298 carrier board. It has (very bright) red status LEDs for the 4 inputs, as well as jumper-enable-able pull-up resistors on the inputs.
    No manual. Can't see the reason for pull-up resistors on the inputs(see other thoughts). For security reasons I would put pullDOWN resistors, if any. Plastic parts of the screw terminals are somewhat loose on my board (I bought only one), but that does not caused any problem. Got the same problem with supplies over 20V as FakeName describes
    At this price it can't get any better! if you are looking for a great h-bridge to control couple motors this is a sure bet
  • Slow but accurate

    - Can be driven from Arduino using the standard stepper motor library.- Has high torque- 2048 steps per revolution gives accurate control- LEDs showing the operation- Driver chip on board comes with the package for easy deployment
    Make sure you have some female-ended connectors to supply power and control signals.
    If you need a strong and accurate stepper motor and don't have a driver yet, this is a good starting point. But if you want more speed, then this might not be the product you are looking for.
  • Good quality product, high torque, low noise

    posted by Flubber

    Runs good. High torque. Low current - measured ~30 to 40mA at 13VDC. Running smooth. Not particularly noisy. Reversed the polarity and motor went other direction. Made experiment on 4V LiIon battery. Motor running much slower. Much less noise. Still very high torque! 18 to 22mA at 4VDC.
    Current varies beteen 27mA and 31mA per revolution at 13V DC.
    Overall, good motor with gearbox, high torque, low RPM for a good price.
  • Just as advertised

    Man these are strong! Great build quality, very good case design. Just as advertised, right down to the length and shaft diameter.
    I'm using this as a motor to roll up/ roll down blinds for a home automation project. Works like a charm and has more than enough power. Be sure your power supply can give it enough current as well as the required 12V.
    If this is what you need, get it. Free shipping can't hurt too!
