Tic T825 USB Multi-Interface Stepper Motor Controller

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 microstep 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

• Comprehensive user’s guide
