DRV8825 Stepper Motor Driver with Aluminum Heat Sink(High current limiting resistance).

DRV8825 Stepper Motor Driver with Aluminum Heat Sink

This product is a breakout board for Texas Instruments’ DRV8825 microstepping bipolar stepper motor driver with R100. It features adjustable current limiting, overcurrent and overtemperature protection, and supports six microstep resolutions (up to 1/32-step). Operating on a power supply range of 8.2 to 45 V, it can deliver around 1.5 A per phase without cooling, and up to 2.2 A with adequate cooling. The pinout and interface are similar to those of the A4988 stepper motor driver, making it a high-performance replacement for many applications.

Additionally, the board comes with an aluminum heat sink to improve heat dissipation.

Features

This text describes the features of a stepper motor driver. Here is a possible rewrite:- You can control the stepper motor with simple step and direction signals.
– You can choose from six step resolutions: full, 1/2, 1/4, 1/8, 1/16, or 1/32.
– You can adjust the maximum current output with a potentiometer. This allows you to use higher voltages than the rated voltage of the stepper motor and achieve faster step rates.
– The driver automatically selects the best current decay mode (fast or slow) for optimal performance.
– The driver can handle up to 45 V of supply voltage.
– The driver has a built-in regulator and can work with 3.3 V or 5 V systems directly.
– The driver has protection features such as thermal shutdown, over-current shutdown, under-voltage lockout, short-to-ground and shorted-load detection.
– The driver has a 4-layer, 2 oz. copper PCB for better heat dissipation.
– The driver has an exposed solderable ground pad on the bottom of the PCB under the driver IC.
