DRV8825 Stepper Motor Driver Module

DRV8825 Stepper Motor Driver Module

The DRV 8825 stepper motor driver carrier serves as a breakout board for TI’s DRV 8825 micro-stepping bipolar stepper motor driver. It offers adjustable current limiting, overcurrent and over-temperature protection, along with six micro-step resolutions (ranging from full-step to 1/32-step). This driver operates within a voltage range of 8.2 to 45 V and can provide approximately 1.5 A per phase without requiring a heat sink or forced airflow, with a maximum rating of up to 2.2 A per coil when additional cooling is supplied. It is advisable to thoroughly review the DRV 8825 datasheet prior to usage of this product.

This stepper motor driver enables the control of one bipolar stepper motor at an output current of up to 2.2 A per coil (refer to the power dissipation considerations section for detailed information). Key features include: a straightforward step and direction control interface, six distinct step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step, adjustable current control that permits setting the maximum current output via a potentiometer, allowing the use of voltages exceeding the stepper motor's rated voltage for enhanced step rates, and intelligent chopping control that automatically chooses the appropriate current decay mode (either fast decay or slow decay). The module supports a maximum supply voltage of 45 V, features a built-in regulator (eliminating the need for an external logic voltage supply), and can interface seamlessly with both 3.3 V and 5 V systems. It includes protections for over-temperature shutdown, overcurrent shutdown, under-voltage lockout, and safeguards against short to ground and shorted load. The board is constructed with a 4-layer design and 2 oz copper.

To effectively control the stepper motor using this driver, you will require several essential components, including:

• Arduino
• Breadboard
• Jumper wires
• Batteries or a power supply

Utilising an Aluminium Heatsink with the DRV8825 Stepper Motor Driver can enhance performance and improve heat dissipation.

Features:

• Simple step and direction control interface
• Microstep resolutions: full-step, 1/2-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
• Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
• Intelligent chopping control that automatically selects the appropriate current decay mode (fast decay or slow decay)
• Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
• Short-to-ground and shorted-load protection
• Adjustable current control allows you to set the maximum current output with a potentiometer, facilitating the use of voltages above the rated voltage of your stepper motor for increased step rates
