The 4A Stepper Phidget is a compact yet powerful stepper motor driver. It 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 advanced over-current protection, failsafe protection, supply voltage monitoring, built-in power guard, thermal protection, and polarity protection.
The 4A Stepper Phidget must be connected to a VINT Hub Phidget to function.
The STC1005 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.
