5pcs A4988 Stepper Motor Driver Module, 35 V 2 A, 1/16 Microstepping, with Heatsink

Integrated Microstepping Driver Core A4988 stepper motor driver module; supports bipolar motors with full, 1/2, 1/4, 1/8, and 1/16 microstepping; STEP and DIR pulse control removes complex phase tables; simplifies motion control for controllerlimited systems; Wide Voltage And Current Capability Motor supply voltage up to 35 V DC; maximum output current up to 2.0 A with Rs 0.1 and proper cooling; low RDS on output stage improves efficiency; suitable for stable torque output in compact motion platforms; Advanced Current Decay Control Automatic selection of slow or mixed current decay modes; mixed decay combines fast and slow decay within fixed offtime; reduces audible noise, improves step accuracy, and lowers power dissipation during highresolution microstepping; BuiltIn Protection And Reliability Includes thermal shutdown with hysteresis, undervoltage lockout, and crosscurrent protection; synchronous rectification reduces heat during PWM operation; no special poweron sequence required, improving reliability during frequent restarts; Logic Level And System Compatibility Logic inputs compatible with 3.3 V and 5 V controllers; works with common control boards such as for Arduinobased motion controllers; red PCB includes heatsink for thermal support; easy to integrate into CNC and printer control setups
