01 — About
What it does
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
Good to know
- 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
