Key Features of A4988 Stepper Motor Driver Module with Heat Sink For 3D Printer (Red)
- Up to 1/16 Microstepping: Achieve ultra-smooth motor motion by selecting full, half, quarter, eighth, or sixteenth step resolution via three MS pins.
- Adjustable Current Control: On-board trimmer potentiometer lets you precisely set the maximum current per phase, protecting your motor and driver from overheating.
- Built-In Overcurrent & Thermal Protection: The A4988 IC automatically shuts down if temperature or current limits are exceeded, safeguarding your electronics.
- Aluminium Heat Sink Included: Pre-packaged heat sink keeps the IC cool during sustained high-current operation, extending module lifespan.
- Compact StepStick Form Factor: Drop-in compatible with RAMPS 1.4, CNC Shield V3, and virtually all popular 3D printer and CNC controller boards.
- Simple 2-Pin Motor Control: Only STEP and DIR signals are needed from your microcontroller to drive a bipolar stepper motor-minimal wiring, maximum convenience.
- Wide Voltage Range: Supports motor supply voltages from 8 V to 35 V, accommodating a broad range of stepper motors and power supplies.
- Sleep & Enable Pins: Reduce power consumption and heat generation by putting the driver into low-power sleep mode when motors are idle.
- Heat Sink Included: Many sellers charge extra or omit the heat sink entirely; ours comes ready to install.
- Proven Reliability: The A4988 is the industry-standard driver used in millions of 3D printers, CNC routers, and laser engravers worldwide.
