The SMD356C is a three-phase motor driver for hybrid stepper motors, supports 16 grades setting for both drive current and stepping subdivision, resolution up to 12000S/R. It is widely used in CNC equipment, sculpturing machine, cutting machine, etc.


  • Wide range voltage input (DC 24V~60V)
  • 16 grades stepping subdivision setting, resolution up to 12000S/R
  • 16 grades drive current setting, adjustable between 1.2A/Phase and 6.0A/Phase
  • Supports three control modes: common cathode, common anode, and differential
  • Supports alerts for undervoltage, overvoltage, overheat, overcurrent
  • Supports phase memory when power down
  • Optical isolation for both I/O signal and input signal
  • When the stepping pulse stops over 100ms, coil current will be halved automatically
  • Comes with development resources and manual (examples for Raspberry Pi, STM32, Arduino)


  • Operating voltage: DC 24V ~ 60V
  • Signal voltage: 4.2V ~ 24V
  • Drive current: 1.2A ~ 6A
  • Signal frequency: =150KHz
  • Control mode: common cathode, common anode, and differential


The SMD356C is suit for medium or small size CNC equipments which requires high resolution, such as:

  • Sculpturing machine
  • Glue dispenser
  • Automatic screw machine
  • Cutting machine
