Note: The STC1000 has been replaced by the STC1002, which has the same function and form factor, but has a maximum motor current of 8 amps.
The STC1000 allows you to control a bipolar stepper motor ( up to 4A). This Phidget connects to your computer through a VINT Hub and requires an 8-30V DC power supply.
|Make sure the power supply is unplugged before attaching or removing wires from the terminal blocks. Failure to do so could cause permanent damage to the Phidget.|
Using motor controllers with large motors can pose a risk for your power supply. If your supply does not have protective features built-in, you can use a Power Guard Phidget to prevent damage from power spikes from back EMF that is generated when motors brake or change direction. We recommend that you use the SAF2000 for any motor with a coil current between 1.5 and 5 amperes, and the SAF1000 for motors above 5A.
The STC1000 can control both unipolar and bipolar motors, but in almost all cases you're better off with a bipolar motor due to their increased power and more precise step angles. If you care about torque, large motors with high gear ratios are your best bet. If you car about speed, motors with no gearbox and high step angles are better. If you want precision, steppers without gearboxes and low step angles are best because while gearboxes do result in smaller steps, they also introduce a flat 1-3 degrees of positional error due to backlash in the gears.

This Phidget is a smart device that must be controlled by a VINT Hub. For more information about VINT, have a look at the VINT Primer. You can use a Phidget Cable to simply and easily connect the two devices. Here's a list of all of the different VINT Hubs currently available:
|Image||Part Number||Price||Number of VINT Ports||Controlled By|
|HUB5000_0||$60.00||6||Local Network (Ethernet or Wi-Fi)|
Use a Phidget cable to connect this device to the hub. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

This Phidget requires a power supply between 10 and 30V DC. We recommend that you use a 12V DC power supply for small steppers and a 24V DC supply for larger ones. If you're not sure, check the data sheet for your motor for the recommended power supply voltage (not to be confused with the coil voltage, which is usually much lower). For best results, we recommend getting a 5 amp supply. Select the power supply from the list below that matches your region's wall socket type.

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 STC1000.
After plugging the STC1000 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.
Control a medium-sized (4A) stepper motor with the STC1000. With this Phidget, you can set your motor's position, velocity, and acceleration.
You can use your Control Panel to explore your Phidget's channels.
1. Open your Control Panel, and you will find the Stepper Phidget channel:
2. Double click on the channel to open an example program. This channel belongs to the Stepper channel class:
In your Control Panel, double click on "Stepper Phidget":
Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.
1. Open the Control Panel and double-click on the red map pin icon:
2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.
