This stepper motor driver board is based on a ULN2003 Darlington transistor array and is designed for driving 4‑phase unipolar stepper motors such as the 28BYJ‑48. The board features four control input pins (IN1–IN4) that connect to a microcontroller to control motor stepping sequences. A dedicated motor connector allows direct connection to compatible stepper motors without additional wiring. Four onboard LED indicators show the active output channels, providing clear visual feedback of motor operation and step sequence status. The module operates on a 5V DC power supply and is suitable for stepper motor control in embedded systems, control experiments, and electronic development projects. Technical Specifications Driver Type: ULN2003 Darlington transistor array Supported Motor Type: 4‑phase unipolar stepper motor Compatible Motor: 28BYJ‑48 stepper motor Operating Voltage: 5V DC Control Inputs: IN1, IN2, IN3, IN4 Motor Interface: 5‑pin stepper motor connector Indicators: 4 × LED output status indicators Control Method: Digital signal control from MCU Board Function: Stepper motor driving and control
