{"product_id":"a4988-stepper-motor-driver-module","title":"A4988 Stepper Motor Driver Module","description":"\u003cp\u003eThe A4988 stepper motor driver module is a widely used compact motor driver board designed to control bipolar stepper motors in robotics, 3D printers, cnc machines, and other automation projects. It integrates the A4988 driver chip, which provides adjustable current limiting, over‑temperature thermal shutdown, under‑voltage lockout, and crossover‑current protection, making it robust and reliable for a variety of applications. The module operates from a\u003cstrong\u003e \u003c\/strong\u003estep\/direction control interface, accepting simple digital pulses from microcontrollers such as Arduino, Raspberry Pi, or similar controllers to drive the motor accurately. It supports microstepping up to 1\/16 step, allowing smoother movement, quieter operation, and finer position control compared to full‑step driving. A small potentiometer on the board allows fine tuning of the motor current to match the specific motor’s rating, helping prevent overheating and improving efficiency. The A4988 module also includes onboard\u003cstrong\u003e \u003c\/strong\u003eheat dissipation features and a compact footprint that makes it easy to integrate into cnc shields, breakout boards, and custom circuits. With straightforward pin headers and clear markings, this driver module is ideal for makers, hobbyists, and engineers seeking precise and efficient control of bipolar stepper motors in a wide range of motion control applications.\u003c\/p\u003e","brand":"Electro Robo Store","offers":[{"title":"Default Title","offer_id":51920733339924,"sku":"MT0482","price":69.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/6590\/0052\/files\/A4988StepperMotorDriverModule.jpg?v=1769599856","url":"https:\/\/electro-robo.com\/products\/a4988-stepper-motor-driver-module","provider":"Electro Robo Store","version":"1.0","type":"link"}
