Pololu Tic T825 USB Multi-Interface Stepper Motor Controller - Pre-soldered connectors
Easily add basic control of a bipolar stepper motor to a variety of projects
Support six different control interfaces
Open-loop speed or position control of one bipolar stepper motor
Selectable microstep modes up to 1/256-step resolution
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 (or 2.5 A max with sufficient additional cooling).
