Tic T825 USB Multi-Interface Stepper Motor Controller (Connectors Soldered)

The Tic T825 USB Multi-Interface Stepper Motor Controller makes basic control of a stepper motor easy, with quick configuration over USB using our free software. The controller supports six control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a TI DRV8825 driver and ships with soldered header pins and terminal blocks. 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.

The Tic T825 USB Multi-Interface Stepper Motor Controller is a versatile, general-purpose controller designed to control one bipolar stepper motor. With a variety of supported interfaces–USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, analog voltages for use with a potentiometer or analog joystick, and quadrature encoder for use with a rotary encoder dial–and a wide array of configurable settings, the Tic T825 makes it easy to add basic control of a bipolar stepper motor to a variety of projects. A free configuration utility (for Windows, Linux, and macOS) simplifies initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

A Micro-B USB cable (not included) is required to connect the Tic to a computer.

Details for item #3130

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 with connectors soldered so no soldering is necessary to use it.
