SMS-304 4 axis stepper motor driver, 2-phase 3.0A CNC microstepping stepper motor controller.

An "Made in EU" SMS 304 4 axis stepper motor controller in a compact SMD version for bipolar 2-phase stepper motors.
Compact design, microstepping and small heat generation - ideal for small and medium size CNC controls.

A 4-axis stepper motor driver for machines with dual X drive or machines with rotary axis.

Integrated power supply, 5 inputs and 2 relay outputs - for quick and easy installation of the step motor controller.
Power supply via a transformer with max. 34V AC generated a motor voltage up to 50V DC.

Excellent performance and dynamics with small and medium-sized motors, such as the
1.1Nm SanyoDenki 103-H7123-0440 or 1.65Nm SanyoDenki 103H7126-0740 and 103H7126-0710.

Also something larger stepper motors are not a problem.
4.0A 3Nm SanyoDenki 103H-7823-1740 and 103H-7823-1741 or 103H-7823-1711 and 103H-7823-1714.

Compatible CNC software for the SMS-304 microstep controller.
