Applications
Key Specifications
Getting Started
Connect a 4.5V to 48V power supply to the VM and GND terminals and attach a bipolar stepper motor to the phase outputs. Use the micro-USB cable to connect the EVM to a Windows PC and run the TI GUI composer application to configure motor parameters and control motion. The onboard SPI interface allows for deep access to the driver settings including decay modes and step resolution.
