DRV8825 Stepper Motor Driver with Heat Sink

<p>The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.</p> <p>The module has a pinout and interface that are nearly identical to those of the A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.</p> <p>The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).</p> <p><img class=""alignnone wp-image-52610"" src=""https://robu.in/wp-content/uploads/2017/12/IMG_0849.jpg"" alt="""" width=""558"" height=""396"" /></p> <p><em><strong>Note:</strong></em> We are supplying two DRV8825 Drivers as DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Good Quality and <a href=""https://robu.in/product/drv8825-stepper-motor-driver-with-aluminum-heat-sink/"" target=""_blank"" rel=""noopener noreferrer"">DRV8825 Stepper Motor Driver with Aluminum Heat Sink- Normal Quality</a><strong>. </strong><em>The difference between them is, the good quality DRV8825 has <strong>more number of </strong><strong>PCB layers</strong> and it features the <strong>connecting pins which are of gold plated</strong> as compared to other. <strong>(refer to above image)</strong></em></p> <p> </p> <h4><u>Using the Driver<br /></u></h4> <p><img src=""http://www.hobbytronics.co.uk/image/data/pololu/drv8825-stepper-motor-driver-4.jpg"" alt=""Wiring diagram for DRV8825 Stepper Motor Driver"" width=""540"" height=""267"" /></p> <hr /> <h4><strong>Features :</strong></h4> <ol> <li>Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.</li> <li>Simple step and direction control interface</li> <li>Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step</li> <li>Adjustable current control lets you set the maximum current output with a potentiometer.
