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.

How to Use
The SKR motherboard connects with the computer via the [USB] interface. After the driver is installed, the motherboard can be inserted into the computer to recognize the port for data transmission. Without the driver installed, it is easy for the computer to not recognize the USB port

1. Smoothieware-usb-driver-v1.1 driver installation (Windows systems only) The driver can be obtained from our open-source network
Https://www.dropbox.com/s/ighnj7oa2l0bm5g/smoothieware-usb-driver-v1.1.exe?dl= 0
2. After installing the driver, connect the computer and SKR motherboard with USB cable
Note: When using smoothieware open-source firmware, since only Windows system drivers, the SKR board at this time can only be recognized by the Windows system port! ! !
3. If you are using Marlin2.0 firmware, follow the tutorial to install:
