If you're looking for a compact solution for controlling a medium-sized stepper motor, the STC1001 is an affordable and convenient option. You can control the position, velocity, and acceleration of the motor by sending commands from your program. This Phidget connects to a VINT Hub; for a list of options see the Connection & Compatibility tab.
The STC1001 comes equipped with a heatsink to prevent the board from overheating during use. The power terminals on this device are polarity protected: if you happen to hook up the power supply backwards, the device simply won't power up and won't be damaged. A 5-amp automotive-style fuse is also included to protect the board from current spikes from the motor's back-EMF. This Phidget is isolated from input to output, so your VINT hub and computer will be protected if anything goes wrong.
Power Saving Options
For power-conscious users, we also allow for separate control over the current limit and the holding current limit. If you know your motor will be stationary for long periods of time, but still needs a small amount of holding torque to maintain its position, you can set the holding current appropriately without interfering with the running current limit.

Using the STC1001
Phidget Control Panel
In order to demonstrate the functionality of the STC1001, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines.
To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel
To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.
For more information, take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the STC1001.
After plugging the STC1001 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on the Stepper object, labelled Stepper Phidget, in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
