28BYJ-48 5V DC Stepper Motor with ULN2003 Driver Board Module for Arduino

The 28BYJ-48 5V Stepper Motor with ULN2003 Driver Board is one of the most popular and affordable solutions for precise rotational control in robotics, automation, and DIY electronics. This geared stepper motor offers high torque and excellent step accuracy despite its compact size. Bundled with the ULN2003 Darlington transistor array driver board, it allows for seamless plug-and-play integration with microcontrollers like Arduino, ESP32, and Raspberry Pi without drawing excessive current directly from the control board.

At Electrapac (www.electrapac.com), we provide original and tested 28BYJ-48 Stepper Motor kits to make your smart locks, automatic blind controllers, and robotics projects highly precise and stable in Bangladesh.

Key Features & Benefits:

• Precision Control: Geared down to offer 64 steps per revolution internally, expanding to 4096 steps per output shaft revolution in half-step mode for micro-stepping precision.

• High Torque Output: The integrated reduction gear ratio of approximately 64:1 significantly boosts output torque for small mechanical loads.

• Plug-and-Play Driver: The ULN2003 board comes with a direct 5-pin JST mating socket for the motor, eliminating complex wiring errors.

• Visual Status Indicators: The driver board features onboard 4-phase LEDs (A, B, C, D) to give real-time visual feedback on which motor coils are energized.

• Safe Microcontroller Driving: Protects your Arduino or ESP32 from inductive kickback currents using the robust ULN2003 chip.

Common Applications:

• Automated Window Blind and Curtain Controllers.

• DIY CNC Projects and Small 3D Printer Feeders.

• Robotic Arms and Pan-Tilt Camera Gimbal Assemblies.

• Smart Home Ventilation Louvers and Automatic Locks.

• Educational STEM Kits and Mechatronics Engineering Prototypes.
