Description:

The Tic T500 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 an MPS MP6500 driver and ships with soldered header pins and terminal blocks. It can operate from 4.5 V to 35 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (or 2.5 A max with sufficient additional cooling).

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).
  • Selectable micro step modes up to 1/256-step resolution:
    • The Tic 36v4 supports full-step to 1/256-step modes
    • The Tic T825, Tic T834, and T249 support full-step to 1/32-step modes
    • The Tic T500 supports full-step to 1/8-step modes
  • 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 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 

 

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.

Note: 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.
