DM556 Microstep Motor Driver - For Nema17/Nema23 Stepper Motors - 20-50V DC, 1-5.6A

Product Introduction – DM556 Digital Stepper Driver

The DM556 is a high-performance digital stepper motor driver, designed to control 2-phase and 4-phase hybrid stepper motors. It supports a wide range of input voltages (20–50VDC) and output currents (up to 5.6A), making it ideal for medium to high-end CNC and automation equipment. The DM556 offers precise and smooth motion control with automatic current reduction, high-speed performance, and low noise, and is compatible with both 4-wire and 8-wire stepper motors (NEMA 23, NEMA 24, NEMA 34).

It is suitable for applications such as CNC routers, laser cutters, 3D printers, robotics, and other industrial automation projects where reliable and precise stepper motor control is essential.
