Advantage:
●HR4988 A4988 was one kind is advantageous for the use interior to integrate the decoder not only to step-by-step the electrical machinery driver
●its design for can cause double to step-by-step the electrical machinery by entire, half, 1/4, 1/8, 1/16 step-by-steps the pattern work
●step-by-steps the pattern to input the MSx choice by logic
●output driving force 38V and ±2A
●HR4988 A4988 contains a work to fade slowly or the mix weaken pattern fixed die-away time current regulator

Features:
●Low breakover resistance RDS(ON)
●The automatic detection and chooses the decay of current pattern
●Supports the slow weaken and the mix weaken pattern
●Reduces the power loss the synchronized rectification function
●The interior owes presses locking
●Overflow protection
●Superheat shutdown electric circuit
●Short-circuits the protection to the place
●Load short circuit protection
●Supports 16 segmentations high

Protection function: The stepper motor drive modules can provide thermal shutdown protection, over current protection, ground fault protection and crossing current protection
Wide application: The stepper motor drive module is compatible with stepper motor/ 3D printer/ CNC/ engraving machine/ supported 3D printer and more; Please confirm whether the product model is suitable before buying
