(-36%)The ULN2003A Stepper Motor Driver (SMD) Module is a high-current transistor array board designed to drive 4-phase unipolar stepper motors. It provides easy and reliable interface between low-power microcontrollers and stepper motors, enabling precise step control.
Product details
The ULN2003A Driver Module (SMD) is designed for controlling unipolar 4-phase stepper motors using low-voltage logic control signals. Built around the ULN2003A Darlington transistor array IC, the module allows the motor to be powered from an external supply while logic signals operate safely at TTL/CMOS levels. It features onboard driver stages that provide high current to each coil of the stepper motor, ensuring efficient torque and stable movement. LED indicators are often provided on each channel to visualize motor step sequence, simplifying debugging and testing. This SMD version has a compact form factor, making it suitable for embedded and space-constrained projects. It is widely used in automation, robotics, camera sliders, CNC systems, and 28BYJ-48 stepper motor–based projects requiring precise positioning.
