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.

Features and specifications
Details for item #3134
The Tic T500 is based on the MP6500 IC from Monolithic Power Systems. This driver IC features automatic decay mode selection, using internal current sensing to automatically adjust the decay mode as necessary to provide the smoothest current waveform. The Tic T500 can operate from 4.5 V to 35 V and can deliver up to approximately 1.5 A continuous per phase without a heat sink or forced air flow (the peak current per phase is 2.5 A). This version is sold with connectors soldered so no soldering is necessary to use it.
Powering the Tic T500 with a supply voltage between 4.5 V and 5.5 V might cause its logic voltage to be lower than normal, which could affect operation. See the user’s guide for more information.
