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

Artikelnummer: PO3130

EAN: 4060137035852

Hersteller-Artikelnr.: 3130

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 8.2 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow.

Overview

The Tic T825 USB Multi-Interface Stepper Motor Controller is a versatile, general-purpose controller designed to control one bipolar stepper motor. With a variety of supported 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?and a wide array of configurable settings, the Tic T825 makes it easy to add basic control of a bipolar stepper motor to a variety of projects. A free configuration utility (for Windows, Linux, and macOS) simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

Details for item #3130

The Tic T825 is based on the DRV8825 IC from Texas Instruments. It can operate from 8.2 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. A version is also available with header pins and terminal blocks included but not soldered.

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).
  • Six different microstep resolutions: full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 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
