Pololu Tic 36v4 USB Multi-Interface High-Power Stepper Motor Controller (Connectors Soldered)

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.

• Comprehensive user’s guide

Details for item #3140

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 Pololu's 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.
