Tic T249 USB Multi-Interface Stepper Motor Controller Pololu

DESCRIPTION

The Tic T249 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using the free software. The controller supports six control interfaces: USB, TTL serial, I2C, analogue voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a Toshiba TB67S249FTG driver with innovative and unique features that include Automatic Gain Control, and male headers and terminal blocks are included but not soldered. It can operate from 10 V to 47 V and can deliver up to approximately 1.8 A per phase without a heat sink or forced air flow (or 4.5 A max with sufficient additional cooling). 

FEATURES

• 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
• Analogue voltage for use with a potentiometer or analogue 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:
• T249 support full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 step
• A digitally adjustable current limit
• Optional safety controls to avoid unexpectedly powering the motor
• Input calibration (learning) and adjustable scaling degree for analogue 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
