The 8A Stepper Phidget is a powerful stepper motor driver that operates on a 10-30V DC and provides up to 8 amps of continuous current per phase to a single bipolar stepper motor.
This controller features two operating modes: Step Mode and Run Mode. In Step Mode, a Target Position is set and the controller intelligently moves the motor toward the target while adhering to the user-specified Acceleration and Velocity Limit. In Run Mode, the controller continuously rotates the motor in the chosen direction, again following the defined Acceleration and Velocity Limit.
There are several built-in safety features, including advanced over-current protection, failsafe protection, and polarity protection.
The 8A Stepper Phidget must be connected to a VINT Hub Phidget to function.
Features
Delivers up to 8A of continuous current per phase to a single bipolar stepper motor.
Supports microstepping with a resolution of 1/16 steps.
Offers advanced current limit settings.
Includes built-in electrical isolation for enhanced system reliability.
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.
The STC1002 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 Overview page. 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:
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.
For installation instructions for these packages, see the README file included with each one.
Step 2: Connect Devices
● Connect USB Cable to your Linux Computer
● Connect VINT Device(s)
Step 3: Verify Connection
1. The easiest way to verify that your libraries are working properly is to compile and run an example program. Download and unpack this C example that will
detect any Phidget:
2. Next, open the terminal in the location where you unpacked the example. Compile and run using:
gcc HelloWorld.c -o HelloWorld -lphidget22
sudo ./HelloWorld
ou should receive a “Hello” line for each Phidget channel that is discovered:
I don’t see any Phidgets show up in the HelloWorld example
You need to run it with sudo in order to be able to access USB devices. In order to use
Phidgets without sudo, you need to set your udev rules. See the Advanced Information page on the final slide of this guide for details.
Done!
If you're able to see your devices in the Hello World example, you're done with the Setup part of this guide.

MacOS users can upgrade device firmware by double-clicking the device row in the Phidget Control Panel.
Linux users can upgrade via the phidget22admin tool (see included readme for instructions).
Windows users can upgrade the firmware for this device using the Phidget Control Panel as shown below.
Firmware Downgrade
Firmware upgrades include important bug fixes and performance improvements, but there are some situations where you may want to revert to an old version of the firmware (for instance, when an application you're using is compiled using an older version of phidget22 that doesn't recognize the new firmware).
MacOS and Linux users can downgrade using the phidget22admin tool in the terminal (see included readme for instructions).
Windows users can downgrade directly from the Phidget Control Panel if they have driver version 1.9.20220112 or newer:
Firmware Version Numbering Schema
Phidgets device firmware is represented by a 3-digit number. For firmware patch notes, see the device history section on the Specifications tab on your device's product page.
If the digit in the 'ones' spot changes, it means there have been bug fixes or optimizations. Sometimes these changes can drastically improve the performance of the device, so you should still upgrade whenever possible. These upgrades are backwards compatible, meaning you can still use this Phidget on a computer that has Phidget22 drivers from before this firmware upgrade was released.
If the digit in the 'tens' spot changes, it means some features were added (e.g. new API commands or events). These upgrades are also backwards compatible, in the sense that computers running old Phidget22 drivers will still be able to use the device, but they will not be able to use any of the new features this version added.
If the digit in the 'hundreds' spot changes, it means a major change has occurred (e.g. a complete rewrite of the firmware or moving to a new architecture). These changes are not backwards compatible, so if you try to use the upgraded board on a computer with old Phidget22 drivers, it will show up as unsupported in the Control Panel and any applications build using the old libraries won't recognize it either. Sometimes, when a Phidget has a new hardware revision (e.g. 1018_2 -> 1018_3), the firmware version's hundreds digit will change because entirely new firmware was needed (usually because a change in the processor). In this case, older hardware revisions won't be able to be upgraded to the higher version number and instead continue to get bug fixes within the same major revision.
