It operates from 8–35V and can deliver up to 2A per coil with adequate cooling. This driver is widely used in 3D printers, CNC machines, and robotics for precise motion control.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMotor Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e8–35V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaximum Current\u003c\/td\u003e\n\u003ctd\u003e2A (with heatsink\/cooling)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrostep Modes\u003c\/td\u003e\n\u003ctd\u003eFull, 1\/2, 1\/4, 1\/8, 1\/16\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLogic Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3–5V\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOvercurrent Protection\u003c\/td\u003e\n\u003ctd\u003eYes, thermal shutdown\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e15.5mm x 20.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e3D printer or CNC machine with precise axis control\u003c\/li\u003e\n  \u003cli\u003eAutomated camera slider for smooth time-lapse shots\u003c\/li\u003e\n  \u003cli\u003eRobotic arm with accurate joint positioning\u003c\/li\u003e\n  \u003cli\u003eDIY plotter or laser engraver for creative projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe A4988 driver is compatible with all major 3D printer control boards like RAMPS 1.4, Arduino Mega 2560, and similar boards using step\/direction control. It works seamlessly with 4-wire, 6-wire, and 8-wire bipolar stepper motors, and can be used with any microcontroller providing step and direction signals.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect motor supply to VMOT and GND, and logic supply (3.3–5V) to VDD and GND. Connect step and direction pins to your microcontroller's digital pins; the enable pin can be tied low to enable the driver. Always use a 100µF decoupling capacitor across motor power supply terminals.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
