Description
The Tic T825 is based on the DRV8825 IC from Texas Instruments. It can be operated from 8.5 V to 45 V and deliver up to approx. 1.5 A per phase without a heat sink or airflow (absolute maximum is 2.5 A per phase).
The stepper motor controller has reverse-voltage protection for motor power supplies up to 40 V. This version is sold fully assembled, so no soldering is required.
A version is also available in which the terminal blocks and header pins are not yet attached and soldering is required.
Features:
- Speed or position control of a bipolar stepper motor
- USB for direct connection to a computer
- TTL serial 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. Allows unlimited full rotation (not intended 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 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 limiting
- Optional safety controls to prevent unexpected power to the motor
- Input calibration and adjustable scaling 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 macOS
