ULN2003A Driver Module Stepper Motor Driver Board
Original price was: ₹50.00.₹31.00Current price is: ₹31.00.
(-38%)The ULN2003A Driver Module Stepper Motor Driver Board is a transistor array–based driver module designed to control 5-wire unipolar stepper motors. It offers reliable high-current and high-voltage driving capability, making it ideal for applications requiring accurate step control using microcontrollers.
Product details
The ULN2003A Driver Module Stepper Motor Driver Board is built around the ULN2003A Darlington transistor array IC, designed to drive unipolar stepper motors efficiently. The module supports 4-phase stepper motors and accepts TTL/CMOS logic levels from controllers such as Arduino, ESP32, STM32, and Raspberry Pi.
It features onboard indicator LEDs to display step sequences during motor rotation, making debugging simple and visual. The module contains seven high-current Darlington transistor channels, out of which four channels are utilized to drive the four coils of the stepper motor. With a built-in flyback diode protection circuit, it ensures safe operation with inductive loads. Compact, stable, and easy to interface, it is widely used in automation, robotics, and precision motion control systems.
