The DQ542MA Stepper Motor Driver is a type of two-phase hybrid stepping motor driver. 

It is designed for use with 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter and less than 4.0A phase current.  

This high power driver is widely used in middle and big size numerical control devices such as curving CNC machine, Computer embroider machine, packing machines and so on.

"The circuit that it adopts is similar to the circuit of a servo controller which enables the motor to run smoothly almost without noise and vibration!"

Compatible with the SmoothieBoard & CNC USB MK3/4 Board.
