Spptty Stepper Motor Driver Module Portable Brand New For Home

Description: A4988 is a complete micro-stepping motor driver with built-in translatorfor easy operation. It includes a fixed off-timecurrent regulator the regulator in slow or mixed decay modes. A4988converter is the key to the easy implementation. As long as the step input inputting one pulse drives the motor one micro-step. There are nophase sequence tables high frequency control lines or complexinterfaces to program. A4988 interface is very suitable for complexmicroprocessor is unavailable or is overburdened. Features: Simple step and direction control interface short-to-ground and shorted-load protection. Five different step resolutions: full-step half-step quarter-step eighth-step and sixteenth-step. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). Over-temperature thermal shutdown under-voltage lockout and crossover-current protection. Adjustable current control lets you set the maximum current output witha potentiometer which lets you use voltages above your steppermotor s rated voltage to achieve higher step rates. Internal synchronousrectification control circuitry is provided to improve the pulse-widthmodulation (PWM) operation power consumption. Specifications: Step Mode: Full half 1/4 1/8and 1/16 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
