Tic T825 USB Multi-Interface Stepper Motor Controller (Connectors Soldered)

Overview

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.

Features and specifications

• Open-loop speed or position control of one bipolar stepper motor
• A variety of control interfaces:
  • USB for direct connection to a computer
  • TTL serial operating at 5 V for use with a microcontroller
  • I²C for use with a microcontroller
  • RC hobby servo pulses for use in an RC system

• Optional limit switch inputs with homing capabilities
• Optional kill switch inputs
• STEP/DIR outputs for controlling external stepper motor drivers
• Connects to a computer through USB via a USB A to Micro-B cable (not included)
• Free configuration software available for Windows, Linux, and macOS
• Arduino library makes it easy to get started using these controllers with an Arduino or compatible board
• Comprehensive user’s guide

Details for item #3130

The Tic T825 is based on the DRV8825 IC from Texas Instruments. It can operate from 8.5 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (absolute maximum is 2.5 A per phase). It has reverse protection for motor power supplies up to 40 V. This version is sold with connectors soldered so no soldering is necessary to use it.
