The Tic family of stepper motor controllers makes it easy to add basic control of a bipolar stepper motor to a variety of projects. These versatile, general-purpose modules support six different control interfaces: USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, analog voltages for use with a potentiometer or analog joystick, and quadrature encoder for use with a rotary encoder dial. They also offer many settings that can be configured using our free configuration utility (for Windows, Linux, and macOS). This software simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB (a micro-B USB cable is required to connect the Tic to a computer).
The table below lists the members of the Tic family and shows the key differences among them.

Basic pinout diagram of the Tic 36v4 USB Multi-Interface High-Power Stepper Motor Controller.
The Tic 36v4 High-Power Stepper Motor Controller uses discrete MOSFET H-bridges, allowing it to control large stepper motors that demand more current than typical integrated drivers can handle, but it matches the compact form factor of our lower-power Tic controllers. It supports nine microstepping modes with as small as 1/256-step resolution, as well as various current decay modes, including an automatic mixed decay mode. The Tic 36v4 can operate from 8 V to 50 V and can deliver up to approximately 4 A continuous per phase without a heat sink or forced air flow (6 A max with sufficient additional cooling). This version is sold with connectors soldered so no soldering is necessary to use it.

Tic Stepper Motor Controller User’s Guide (Printable PDF)
User’s manual for the Pololu Tic USB Stepper Motor Controller.
Getting up and running with your Tic stepper motor controller from Pololu is easy. This video will guide you through the basic steps to connect your Tic to its software and control a stepper motor from your computer.
Yes. To avoid damaging your stepper motor, you want to avoid exceeding the rated current, which is 600 mA in this instance. The Tic T825 stepper motor controller has configurable current limiting, so you can set a limit that is appropriate for your stepper motor. As long as you set the limit below the rated current, you will be within spec for your motor, even if the voltage exceeds the rated voltage. The voltage rating is just the voltage at which each coil draws the rated current, so the coils of your stepper motor will draw 600 mA at 3.9 V. By using a higher voltage along with active current limiting, the current is able to ramp up faster, which lets you achieve higher step rates than you could using the rated voltage.
If you do want to use a lower motor supply voltage for other reasons, consider using the Tic T500, which operates from 4.5 V to 35 V, or the Tic T834, which operates from 2.5 V to 10.8 V.
