DRV8825 stepper motor driver

The DRV8825 stepper motor driver can drive one bipolar stepper motor at up to 2.2A with adequate cooling. The module can easily handle 1.5A with no heatsink. A small heatsink is included and with a little air flow, it can handle up to the full 2.2A. Note that the driver IC can handle up to 2.5A, but the 0.1 ohm current sense resistors limit the output to 2.2A.

It is packaged onto a small board with male headers installed in a wide DIP-16 footprint that makes it breadboard compatible or it can be mounted into a socket. These are often used for precision control of stepper motors used in applications such as 3D printers or robotics.

FEATURES OF DRV8825 HIGH CURRENT STEPPER MOTOR DRIVER MODULE:

• 2.2A current handling capability
• Small footprint
• Easy step and direction control interface
• Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
• Adjustable current control lets you set the maximum current output with a built-in potentiometer. That allows you to use voltages above your stepper motor’s rated voltage to achieve higher step rates
• Adjustable current decay modes.
• Built-in regulator so no external logic voltage supply is needed
• Can interface directly with 3.3 V and 5 V systems
• Over-temperature shutdown, over-current shutdown, and under-voltage lockout with FAULT pin output
• Short-to-ground and shorted-load protection

PACKAGE INCLUDES:

• DRV8825 High Current Stepper Motor Driver Module
• Heat sink
