{"title":"Adafruit A4988 Stepper Motor Driver Breakout Board","handle":"adafruit-a4988-stepper-motor-driver-breakout-board-ada6109","url":"/products/adafruit-a4988-stepper-motor-driver-breakout-board-ada6109","description":"The Adafruit A4988 Stepper Motor Driver Breakout simplifies stepper motor control down to just two pins — a direction pin and a step pin. Each pulse on the step pin advances the motor by one step or microstep, making it straightforward to achieve precise, controlled motion without complex timer or PWM setups.\n\nBuilt around the Allegro A4988 driver IC, this breakout supports motor voltages from 8V to 35V DC and logic levels from 3V to 5V, making it compatible with Arduino, ESP32, Raspberry Pi and other popular microcontrollers. The board features terminal blocks for easy motor and power wiring, and a 2 oz copper PCB for improved current handling and heat dissipation.\n\nKey Features\n\n\nTwo-Pin Control – DIR sets rotation direction, STEP advances one step/microstep per pulse\n\nMicrostepping – Default 1/16 microstep mode, adjustable to full step, 1/2, 1/4 or 1/8 via MS1/MS2/MS3 pins\n\nAdjustable Current Limit – Up to 2A via on-board potentiometer (heatsink recommended for high-current use)\n\nWide Motor Voltage Range – 8–35V DC input for stepper motors\n\n3–5V Logic Compatible – Works with Arduino, ESP32, Raspberry Pi and more\n\nLED Indicators – Red and green LEDs show direction, yellow LED indicates step pulses\n\nOvercurrent Protection – Built into the A4988 driver IC\n\nTerminal Blocks – Screw terminals for motor and power connections\n\nControl Lines – Sleep, Reset and Enable pins for power management\n\n22 µF 50V Capacitor – On-board capacitor for motor power stability\n\nFour Mounting Holes – For secure mechanical attachment\n\n\nIdeal For\n\nCNC machines and 3D printers\nRobotics with precise positioning\nCamera sliders and pan/tilt systems\nAny application requiring controlled stepper motor movement\n\n\nPackage Contents\n\n1× Adafruit A4988 Stepper Motor Driver Breakout Board\n1× Header strip\n\n\n\nNote: Stepper motor, power supply and heatsink are not included. Some light soldering is required to attach the included header pins.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":673,"title":"Default Title","sku":"AF-6109","mpn":"ADA6109","price":13.65,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":37,"option1":"Default Title"}]}
