Chip upgrade Using the latest high-quality chips, higher compatibility and better conductivity.(It is believed that only high quality products can ensure the quality of your work and bring safety to your work.)

Product Features

  • 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.
