The Tic T825 is based on the DRV8825 IC from Texas Instruments. It can operate from 8.5 V to 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (absolute maximum is 2.5 A per phase). It has reverse protection for motor power supplies up to 40 V. This version is sold unassembled so soldering is necessary to use it.
A version is also available that requires no soldering to use as the terminal blocks and main header pins are already installed.
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
- 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).
- Six different microstep resolutions: full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 step
- 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 kill switch inputs
- 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
