    Hello.

    Unfortunately, we only offer assistance in English. A distributor near you might be able to offer you help in another language. You can find a list of our distributors here:

    Hi, Vijay.

    You can enable subtitles for the video by clicking on the settings button at the bottom right corner of the YouTube video's user interface overlay. You might also find it helpful to read the "Current limiting" section of our stepper motor driver carrier product pages, for example:

    Hi, Gino.

    We do not commit to or disclose the components used on our G2 high-power motor drivers.

    Hi, David.

    The D24V50F5 should be able to handle the combined ~3.5A draw of your Raspberry Pis. I don't have any specific recommendations for a LiPo battery, but anything 2S or more that has enough instantaneous current output and capacity for your application should be fine. If you are new to selecting batteries, this blog post about battery capacity might be helpful. If you have more questions about how to use that regulator in your project or general electronics questions, you might consider posting them on our forum.

  • New revision of the Dual VNH5019 motor driver shield for Arduino

    New revision of the Dual VNH5019 motor driver shield for Arduino

    - 22 February 2016

    Hi, Criz.

    You could use a 6V motor with the VNH5019, and I think that all of our 6V gear motors have stall currents under 12A, so the VNH5019 should be able to handle their current draw. In this case, the thing to note is that using a brushed DC motor with a voltage that is higher than its rated voltage will increase its performance (speed and torque), but will also increase the current draw and decrease the motor's lifetime.

    The driver will go into brake mode for about 25us once the current chopping threshold is reached. We have updated the description on the product pages for our Pololu G2 High-Power Motor Drivers to include that information as well.

    Hi, nd.

    We don't currently have anything in the works. What features are you looking for that aren't already provided in existing Bluetooth LE boards?

    Hi, NATTHAPONG.

    The G2 High-Power Motor Driver 24v13 can be used at 100kHz with locked-antiphase control. Whether a heat sink is needed for your application will depend on your motor and the load you put on it. However, the specifications we give on the driver's product page are for operation at ambient room temperature without a heat sink.

    Hi, Pierre.

    The video has captions that you can turn on by clicking the CC symbol in the bottom right corner of the video's pop-up user interface. You can also access different settings for the captions (like different languages) by clicking the gear symbol to the right of the CC symbol. If you want to see all of the captions from the video at once, you could select "Transcript" from the "More" menu which can be found just above the video's description if you are viewing the video directly on YouTube.
