Stepper Motor(28YBJ-48) with ULN2003 Driver Board

The Stepper Motor (28YBJ-48) with ULN2003 Driver Board provides precise incremental rotation for position-controlled applications. The included ULN2003 driver board makes it easy to control from Arduino using just 4 digital pins.

Key Features

• 28BYJ-48 stepper motor with 64:1 gear reduction
• ULN2003 driver board included and pre-wired
• 5V operation compatible with Arduino
• 5.625° per step (64 steps/revolution motor, 4096 steps with gearbox)
• Unipolar 4-phase motor for easy control
• Compact size for embedded applications
• High torque at low speeds due to gearbox

Technical Specifications

Applications

• 3D printer extruders and axis control
• CNC machine positioning
• Camera sliders and pan mechanisms
• Automated blinds and curtains
• Fluid dispensing systems
• Precision positioning platforms

Important Notes

• Use Stepper library or AccelStepper for Arduino control
• Motor gets warm during continuous operation – this is normal
• Reduce speed for higher torque applications
• ULN2003 can drive one 28BYJ-48; use separate driver for additional motors
• For higher performance, consider A4988 + bipolar NEMA17 upgrade
