This driver has a same pin and interface as our A4988 stepper motor driver, so it can replace the A4988 driver. It is a high-powered stepper motor driver. </p><p>DRV8825 has adjustable current limits, over-current and over-heat protection, six micro resolution (down 1/32-step).</p><p>It uses 8.2-45V and can provide up to approximately 1.5 per phase without heat sink or forced air flow (rated up to 2.2 with adequate additional cooling per coil)</p><p> </p><h2 data-id="specifications%3A"><strong>Specifications:</strong></h2><p>1. With only simple step and direction control interface;</p><p>2. Six different step modes: full, half, 1/4, 1/8, 1/16, and 1/32;</p><p>3.Adjustable potentiometer can adjust the maximum current output, resulting in a higher step rate;</p><p>4. Automatic current decay mode detection / selection;</p><p>5. Overheat shutdown circuit, under voltage lockout, cross current protection;</p><p>6. Ground short circuit protection and load short circuit protection.</p><p><strong> </strong></p><h2 data-id="settings-for-working-mode%3A"><strong>Settings for working mode: </strong></h2><div class="embedExternal embedImage display-medium float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/ECGWJMRWVWUW/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/ECGWJMRWVWUW/image.png" alt="image.png" height="445" width="672" loading="lazy" data-display-size="medium" data-float="none"></img></a> </div> </div> <h2></h2><h2 data-id="connection-diagram"><strong>Connection Diagram</strong></h2><div class="embedExternal embedImage display-medium float-none"> <div class="embedExternal-content"> <a class="embedImage-link" href="https://us.v-cdn.net/6031942/uploads/VAAVFCZDOGA6/image.png" rel="nofollow noreferrer noopener ugc" target="_blank"> <img class="embedImage-img" src="https://us.v-cdn.net/6031942/uploads/VAAVFCZDOGA6/image.png" alt="image.png" height="407" width="665" loading="lazy" data-display-size="medium" data-float="none"></img></a> </div> </div> <p><br></p><h2 data-id="sample-code"><strong>Sample Code</strong></h2><pre class="code codeBlock" spellcheck="false" tabindex="0">int dirPin = 7; int stepperPin = 8; void setup() { pinMode(dirPin, OUTPUT); pinMode(stepperPin, OUTPUT); } void step(boolean dir,int steps){ digitalWrite(dirPin,dir); delay(50); for(int i=0;i<steps;i++){ digitalWrite(stepperPin, HIGH); delayMicroseconds(800); digitalWrite(stepperPin, LOW); delayMicroseconds(800); } } void loop(){ step(true,1600); delay(500); step(false,1600*5); delay(500); } </pre><h2 data-id="test-result"><strong>Test Result</strong></h2><p>The selection end MS1, MS2, MS3 of three modes are all connected to GND, that is, full-step mode, and the motor needs 200 stepping values or a stepping 1.8° to turn a round.</p><p>In the experiment, we first let the stepper motor reverse 8 circles and delay 0.5 seconds; then turn 40 circles and delay 0.5 seconds. </p><p>If it is an half-step mode, then the number of both positive and reverse circle should be halved.</p><p><br></p><h2 data-id="package-included"><strong>Package Included</strong></h2><ul><li>Inland 3D Printer DRV8825 *5PCS</li></ul> </article> </main>
