The PhidgetStepper Bipolar HC is a powerful stepper motor driver that operates on 10-30V DC and provides up to 4 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, users set a Target Position, 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 over-current protection and polarity protection.
The PhidgetStepper Bipolar HC connects directly to a computer via USB.
Note: The 1067_0B is identical to the 1067_0, except that you have the option of whether you want to include the USB cable.
The 1067 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 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.

The PhidgetStepper Bipolar HC comes with a 5 amp automotive fuse.
Use a USB cable to connect this Phidget to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.

Use the Phidget Control Panel to explore your device's functionality. Each channel is described below.
For the motors sold at Phidgets, you can simply wire the motor as follows:
If your motor has an unknown pinout, you can find out which wires share a coil by using a multimeter in resistance or conductivity mode.
If you want the default direction of rotation to be reversed, switch either the A and B or the C and D wires.
In a 6–wire bipolar motor, there are two + wires, one for each coil, which are the center taps for each coil. You will need to isolate which are the center tap wires and the corresponding wires for their coil.
These center taps are left unconnected when using the 1067. Check the datasheet for your motor to find out which wires are the center taps and connect the remaining wires as if it were a 4-wire motor.
If you don't know the pinout of your motor, you can use a multimeter to determine which wires belong to the same coil and which ones are the center taps. Use conductivity mode to determine which wires are connected to the same coil. Then, use resistance mode to check the values between each of the wires in the same coil. The center tap is the wire that has a lower resistance between the other wires.
Check the datasheet for your motor to determine which wires belong the the same coil, and which coils are paired.
8 Wire Motors are very difficult to wire up if you do not have a schematic showing how the wires are connected to the internal coils. You can use a multimeter to determine which wires pair to the same coil, but you'll need to run the motor trial-and-error to determine which coil pairs with the other.
You can wire an 8-wire stepper in series or parallel. Series wiring will result in higher torque when the motor is stopped or at low speeds. Parallel wiring will provide better torque at higher speeds, but less torque overall. Since the current in parallel mode is split between two paths, the current rating is doubled.
Firmware Upgrade
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.
