Compared with ordinary A4988, our high quality A4988 drive production process is improved again by PCB gold plate process (gold-plated pin) SMT placement machine manufacturing, non-manual welding, higher yield and more stable performance.
Performance upgrade: PCB covering copper process upgrade to 2oz (our high-quality copper thickness 70um, ordinary 35um), higher copper content, better heat dissipation performance.
Under 2A current, it can work for a long time. It is very suitable for 3D Printer? Mendel, Huxley and other machines.
Using the latest chips, higher compatibility and better conductivity
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 toachieve higher step rates.
