Tic T825 USB Multi-Interface Stepper Motor Controller Pololu

DESCRIPTION

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, analogue voltage (potentiometer), quadrature encoder, and hobby radio control (RC). This version incorporates a TI DRV8825 driver and male headers and terminal blocks are included but not soldered. 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 (or 2.5 A max with sufficient additional cooling).

The 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, analogue voltages for use with a potentiometer or analogue 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 the initial setup of the device and allows for in-system testing and monitoring of the controller via USB.

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 (the absolute maximum is 2.5 A per phase). It has reverse protection for motor power supplies up to 40 V.

Please Note:

• This version is sold unassembled so soldering is necessary to use it.
