TIDRV8825EVM
Overview
The DRV8825EVM is an evaluation module designed to demonstrate the capabilities of the DRV8825 bipolar stepper motor driver. This board provides a complete hardware platform for driving a single bipolar stepper motor at voltages from 8V to 45V and currents up to 2.5A. It includes an onboard MSP430 microcontroller to manage the logic and an easy-to-use graphical user interface for motor configuration.
Why Choose This Part
The module features an integrated indexer that simplifies control by allowing the user to manage motor steps with simple Step and Direction pins. It supports up to 1/32 microstepping for reduced vibration and improved positioning accuracy. The onboard PWM current regulation and 45V rating make it suitable for high-torque applications that demand significant thermal headroom.
Applications
Key Specifications
Getting Started
To begin evaluation, connect a 8V to 45V power supply to the VM/GND terminals and a bipolar stepper motor to the A/B phase outputs. Use the provided USB interface and TI's graphical user interface (GUI) to configure current limits and step modes without writing code. For custom firmware development, the board's header pins allow direct access to the DRV8825 control signals for use with an external MCU.
