A4988 tepping Stepper Step Motor Driver Module 3D Printer Parts

About this item

• Description: A4988 is a complete microstepping motor driver with builtin translator for easy operation. It includes a fixed offtime current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the step input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. Features : Simple step and direction control interface, shorttoground and shortedload protection. Five different step resolutions: fullstep, halfstep, quarterstep, eighthstep, and sixteenthstep. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). Overtemperature thermal shutdown, undervoltage lockout, and crossovercurrent protection. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor s rated voltage to achieve higher step rates. Internal synchronous rectification control circuitry is provided to improve the pulsewidth modulation (PWM) operation power consumption. Specifications: Step Mode: Full, half, 14, 18 and 116 Output Driver Capacity: 35V, +2A Driver Size: 20 x 15mm 0.78 x 0.59 Heat Sink Size: 5 x 5mm 0.19 x 0.19 Package Includes: 1 x Driver module 1 x Heat Sink Simple step and direction control interface, shorttoground and shortedload protection Five different step resolutions: fullstep, halfstep, quarterstep, eighthstep, and sixteenthstep Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) Overtemperature thermal shutdown, undervoltage lockout, and crossovercurrent protection Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor rated voltage to achieve higher step rates
