Tic T500 USB Multi-Interface Stepper Motor Controller (Connectors Soldered)

The Tic T500 USB multi-interface stepper motor controller allows easy control of a stepper motor with quick configuration over USB using Pololu's free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder and hobby radio control (RC). It can operate from 4.5 V to 35 V and can deliver up to 1.5 A per phase without a heat sink or forced airflow (or 2.5 A max with sufficient additional cooling).

Features and specifications:

• Speed or position control of a bipolar stepper motor
• USB for direct connection to a computer
• TTL serial operation 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 an analog joystick
• Quadrature encoder input for use with a rotary encoder, allowing unlimited full rotation (not for position feedback)
• STEP / DIR inputs for compatibility with existing stepper motor control firmware
• Acceleration and deceleration limiting
• Maximum step rate: 50,000 steps per second
• Very slow speed down to 1 step every 200 seconds (or 1 step every 1428 seconds with reduced resolution).
• Supports full step, half step, 1/4 step, 1/8 step
• Digitally adjustable current limit
• Optional safety controls to avoid the motor being switched on unexpectedly
• Input calibration (learning) and adjustable scaling degree for analog and RC signals
• 5 V regulator (no external logic power supply required)
• Optional kill switch inputs
• Connects to a computer via USB using a USB A-to-Micro-B cable (not included)
• Free configuration software for Windows, Linux and Mac OS
