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 Pololu's 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.

Details for item #3139

The Tic T249 is based on the TB67S249FTG IC from Toshiba, which allows the Tic T249 to offer several unique and innovative features. One of these is Toshiba’s Active Gain Control (AGC), which automatically reduces the stepper motor current below the set limit based on the actual load on the motor, allowing for reduced unnecessary heat generation and higher peak power when the motor actually needs it. Another is Toshiba’s Advanced Dynamic Mixed Decay (ADMD) technology, which dynamically switches between slow and fast decay modes based on the actual motor current, providing higher efficiency and smoother steps at high speed than you get with traditional timing-based mixed decay.

The Tic T249 can operate from 10 V to 47 V and can deliver up to approximately 1.8 A continuous per phase without a heat sink or forced air flow (the peak current per phase is 4.5 A). This version is sold unassembled so soldering is necessary to use it.

Tic T249 USB Multi-Interface Stepper Motor Controller (without connectors soldered) with included headers and terminal blocks.

A version is also available that requires no soldering to use as the terminal blocks and main header pins are already installed.
