Video: Setting the Current Limit on Pololu Stepper Motor Driver Carriers
- 13 June 2016Thank you for the feedback. What potentiometer(s) do you like?

New MOSFET-based power switches
- 31 May 2016Hi, Hu.
Our pushbutton power switches have an OFF input which allows a microcontroller powered by the switch to turn off its own power.

Video: Setting the Current Limit on Pololu Stepper Motor Driver Carriers
- 27 April 2016Hi, 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:

New Product: 5V, 5A Step-Down Voltage Regulator D24V50F5
- 18 March 2016Hi, 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
- 22 February 2016Hi, 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.

New product: G2 High-Power Motor Driver 24v13
- 4 January 2016The 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.

- 31 December 2015Hi, 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?
