The 28BYJ-48 Stepper Motor with ULN2003 Driver Board Kit (5V) pairs a geared unipolar stepper motor with a matching driver board, giving makers precise, repeatable rotation for cameras, dials, and small mechanisms right out of the box. The driver plugs directly into the motor’s 5-pin connector, so no extra wiring is needed to start stepping.
Key features:
- Motor: 28BYJ-48 4-phase unipolar stepper motor with a 1:64 gear reduction for high torque at low speed.
- Driver Chip: ULN2003 Darlington transistor array drives all four motor phases directly from microcontroller logic pins.
- Step Angle: 5.625 degrees per step, reduced to about 0.088 degrees after gearing.
- Operating Voltage: 5V DC for both the motor and driver board.
- Indicators: Four onboard LEDs show the active phase while stepping, useful for debugging.
- Compatibility: Works with Arduino, Raspberry Pi, STM32, and other microcontrollers via a 4-pin control header.
This ready-to-go combo is a favorite for camera sliders, small CNC-style builds, and any project that needs low-cost, precise rotational control.
