Purelogic RnD(Russia) glad to introduce featured stepper motor drivers PLD545-G3 and PLD-86
Both of them have following features



Auto Resonance Compensation(mid-band and low-band). Do not require adjusting.
Microstep: 1:4,1:8,1:16,1:32

Phase-currents morphing technology optimizes torque on high speeds, and allows to get up to 30% more power from stepper motor.

Built-in EMF dumper protects device from back EMF
Optoisolated inputs
Advanced 4-layer PCBA and firmware provides smooth, low-noise motion.
Over-current, over-voltage, short circuit, overheat, reversed polarity protection
Automatic idle-current reduction(Autosleep mode)
Built-in STEP generator allows you make tests of motors easily

Stepper motor soft start excludes eliminates stepper motor shaft strike on start
