Stepper Motor Driver MKS LV8729

The MKS LV8729 is a high quality replacement for the A4988 stepper driver.  It has similar current rating of the A4988, but is a lot more quiet and smooth and can run up to 1/128 micro stepping.  Compatible with all standard 3D Printer Controller boards.  Ideal for 3D printer, laser cutter, foam cutter and small CNC machine.

Stepper Motor Driver MKS LV8729 Specifications:


  • Voltage supply: 6 - 36V

  • Current rating: 1.5A Maximum

  • Micro stepping: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128.

  • Heat sink included

  • It is recommended to have forced airflow of the stepper driver for cooling when running.


The micro stepping are set according to the chart below:
