New product: VL6180X Time-of-Flight Distance Sensor Carrier
- 8 March 2017Hello, Mike.
This thread on our forum has some code that shows how multiple sensors can be initialized. If you have any further questions, I recommend making a new post on our forum, which is our preferred way of troubleshooting code.

New product: VL53L0X Time-of-Flight Distance Sensor Carrier
- 30 November 2016Hello, Thomas.
There is 48k ohms of resistance between the 2.8V VDD rail and the XSHUT pin on the header. We would expect that resistance to draw about 60uA when the XSHUT input is grounded. You can refer to the schematic diagram on our product page for more information about how that pin is connected.
If you want more help in determining the best way to put the sensor into standby, our forum is the best place to post your questions.

Nathan's line following robot: Suckbot
- 23 November 2016Hello.
I haven't published the files anywhere because they are kind of specific to the parts I used (like the fan blades and motor), there are some bugs in the design (like the front sensor mount being taped on) and in general, it doesn't seem like it is easy to modify STL files. Is there some easy way to work with STL files I'm unaware of?

New products: Magnetic quadrature encoders for micro metal gearmotors
- 8 August 2016Hello, Tom.
The rise time for the signals is very quick and the maximum signaling rate for the encoder is generally limited by the speed of the microcontroller processing the signals.

New high-current stepper driver carrier with SPI: AMIS-30543
- 3 May 2016Hello.
The step angle is a property of the physical configuration of the stepper motor and the signaling method the driver uses to step the motor is not dependent on that physical configuration. Because of this, our stepper library and examples deals with movement in steps rather than angles, though you can write code to take an angle and translate it to the appropriate number of steps. So with your 50 step/rev motor and the driver in full step mode, each step is 7.2 degrees.
By the way, I noticed you posted a similar topic on our forum. I have posted this response there as well and if you have additional questions, that is probably a better place to continue this conversation.

Hexapod robot running ROS
- 1 March 2016Hello.
The comments section of our blog posts is not the most appropriate place for troubleshooting. If you post more details about your robot and what you are having troubles with on our technical support forum, we might be able to help you out.

New products: Assembled Zumo 32U4 robots
- 28 October 2015Hello, Al.
Our forums are generally a better place to do troubleshooting like this. Please post some some sample code and the error message there, and we should be able to help you out.

Nathan's line following robot: Suckbot
- 10 July 2015Hello.
I used the larger battery for the contest because I was doing testing with it and adjusting parameters just before the contest started and I did not want to throw the robot off by changing to the smaller battery at the last minute. I did not extensively characterize the battery life, but the 500mAh battery was enough for at least a few 10's of laps.
There is a short clip of the robot running in the video for the competition at 2:33. Thanks for asking about it.

- 6 July 2015Hello.
You can look at this blog post for some example Arduino code for stepping a motor and a video that shows how to get started with our stepper driver carriers. If you have any additional questions about connecting or using an A4988 carrier, please post them on our technical support forum.

New revision of the Dual VNH5019 motor driver shield for Arduino
- 5 May 2015Hello, Dai.
We do not know of a driver or library for the Intel Edison and this shield.
