New revision of the Dual VNH5019 motor driver shield for Arduino
- 16 January 2020Hello, Pratik.
Yes, all the control pins are broken out along the left side of the board to enable use as a general-purpose motor driver controlled by devices other than Arduinos. Section 4 of the user's guide has more information on that.

New product: USB 2.0 Type-C Connector Breakout Board
- 1 May 2019All the grounds on that board share a common ground plane, so yes, you can just connect to the bottom one.

New product: USB 2.0 Type-C Connector Breakout Board
- 29 April 2019Please note that our company's name is Pololu, not "Polulu". This level of troubleshooting or product support is getting to be beyond what is appropriate for blog comments, and it is also beyond what we can support directly. You might consider posting on our support forums to see if someone in the community has some suggestions:

New product: USB 2.0 Type-C Connector Breakout Board
- 24 April 2019Hello,
If you are using this strictly for power, you would only need to wire VBUS and GND to the appropriate pins/lines on your 32U4 Feather. The Feather appears to have a pin labeled USB that is a connection point for its USB bus voltage. If you additionally want to pass USB data through the Type-C connector, you would have to connect the D+ and D- lines as well. These would probably have to be connected through the Feather's on-board USB receptacle, since it does not provide alternate places to connect those.
We do not carry an adapter cable like the one you are describing, and I do not have a suggestion on where you would be able to find one. However, you might also consider using a USB Micro-B plug breakout board, such as this one from SparkFun:

Bigger 3D printed buttons for the Zumo 32U4
- 18 February 2019Hello.
It is really awesome to hear that this print worked out for you! We would love to hear what you think after the kids get a chance to use them, too.

New D24V150Fx 15A step-down voltage regulator family — our highest-power regulators yet!
- 6 December 2018Hello,
We do not carry right-angle male header pins in that size, and I do not have a specific suggestion for a supplier.
Please note, our header pins can only handle about 3A per pin, so if you are running more than 6A for your setup, it would be better to do something like use the supplied terminal blocks or solder wires directly to the board.

New revision of the Dual VNH5019 motor driver shield for Arduino
- 16 November 2018Hello, Sameer.
The VNH5019 can supply 12A continuously per motor. To be safe, we recommend using a driver that can continuously handle the stall current of your motor. 140mV/A is the scaling factor for the board's current sense output. You can find information about the VNH5019 current sensing feature in the "Current sense outputs" section of the "Pololu Dual VNH5019 Motor Driver Shield User’s Guide", which is located under the Resources tab of its product page.

New Product: Dual TB9051FTG Motor Driver for Raspberry Pi
- 2 November 2018Hi, Jesus.
The Raspberry Pi only has two PWM channels, so even if you could stack multiple motor driver expansion boards, the Raspberry Pi wouldn't be able to generate the signals needed to control them all.
If you want to control 8 motors independently, you might consider our Simple Motor Controllers, which can be daisy chained together and controlled by TTL serial commands from the RPi. You would need one SMC per motor.
https://www.pololu.com/category/94/pololu-simple-motor-controllers
By the way, we will be releasing new SMC versions (the SMC G2) in the next few days that offer an I2C interface in addition to TTL serial.

Beacon Locating Robot - Powered by Arduino and IR Transceiver
- 23 October 2018Hi.
Thank you for pointing that out. We took out the bad link and replaced it with links to video of the robot on YouTube and code for the robot on GitHub.
You might try to reach out to the maker of the robot on their YouTube channel if you have any questions.
