4pcs/lot LV8729 step motor driver（free shipping by air parcel）

 

Name: MKS LV8729

 

Overview
MKS LV8729 is a  ultra quiet stepper motor driver, and good for Nema stepper motor whose current is less than 1.5A, which makes motor steady, quiet and precise.
Also, it does good work with MKS ROBIN, MKS GEN,MKS SBASE and RAMPS1.4 controller board on 3d printer, carving machine, CNC, etc.
