Description [Hide]

The Tic T825 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a TI DRV8825 driver and ships with soldered header pins and terminal blocks. 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.

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).

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
  • Analog voltage for use with a potentiometer or analog joystick
  • Quadrature encoder input for use with a rotary encoder dial, allowing full rotation without limits (not for position feedback)
  • STEP/DIR inputs for compatibility with existing stepper motor control firmware
  • Acceleration and deceleration limiting
  • Maximum stepper speed: 50,000 steps per second
  • Very slow speeds down to 1 step every 200 seconds (or 1 step every 1428 seconds with reduced resolution).
  • Up to six different microstep resolutions:
  • The Tic T825 and Tic T834 supports full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 step
  • The Tic T500 supports full step, half step, 1/4 step, 1/8 step
  • Digitally adjustable current limit
  • Optional safety controls to avoid unexpectedly powering the motor
  • Input calibration (learning) and adjustable scaling degree for analog and RC signals
  • 5 V regulator (no external logic voltage supply needed)
  • Optional kill switch inputs
  • 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
  • Comprehensive user’s guide

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.
