Take your Arduino and microcontroller projects to the next level with the 28BYJ-48 DC gear stepper motor paired with the ULN2003 driver board. This compact, reliable 4-phase stepper delivers precise, repeatable motion for small robotics, automation, and educational kits. With a robust gear reduction and a 5V DC supply, you’ll get fine control without complex wiring or power management. Key features that matter in real projects
- 5V DC operation with a 4-phase unipolar design: simple, widely compatible with Arduino, Raspberry Pi GPIO, and other microcontrollers
- 1/64 gear reduction yields ultra-precise output: 5.625° step angle at the motor shaft, equating to 0.0879° per full step at the final output for about 4096 steps per revolution
- Built-in ULN2003 driver compatibility: wire directly to the driver board and drive with standard step pulse signals
- Durable electrical specs: coil resistance around 200 Ω ±7% (25°C); insulation resistance >10 MΩ (500V); dielectric strength 600V AC / 1 mA / 1 s
- Wide operating temperature: -40°C to +85°C, suitable for varied hobby and educational environments
- Measured performance thresholds: no-load pull-in frequency > 600 Hz; no-load pull-out frequency > 1000 Hz; pull-in torque > 34.3 mN·m (120 Hz); detent torque > 34.3 mN·m
- Quiet operation and compact footprint: less than 40 dB noise under typical no-load conditions at 120 Hz, with a compact board size around 29 × 21 mm Why this motor is a standout for hobbyists and makers
- Unparalleled resolution in a small package: the 1/64 reduction ratio means you get extremely fine positioning without bulky gearing or expensive drivers. It’s ideal for miniature robotics, precise pan/tilt mechanisms, automated cassettes, and small CNC or engraving projects.
- Arduino-friendly workflow: the ULN2003-driven module is designed for straightforward control. Use standard step commands or common libraries (like AccelStepper) to implement smooth acceleration profiles and accurate positioning.
- Durable, reliable design for education and experimentation: wide temperature tolerance and solid insulation specs mean you can prototype in classrooms, benches, or workshops without worrying about edge-case conditions. Practical use cases and setup tips
- Robotics: create a compact rover or robotic arm with precise micro-positioning for grippers or sensors.
- Camera and light control: build a tiny tilt/shake mechanism for time-lapse photography or stage lighting with repeatable presets.
- Educational kits: teach stepper motor fundamentals, torque, gear ratios, and motion control using real hardware and hands-on labs.
- Prototyping: test motion profiles and positioning routines on a low-cost platform before upgrading to larger motors. What makes this solution better than bare motors
- Convenience: the ULN2003 driver board is integrated into the ecosystem, reducing the guesswork around drive electronics and wiring.
- Predictable performance: the documented pull-in/pull-out frequencies and torque values give you clear expectations for response times and load handling in real projects.
- Proven compatibility: proven success with 5V microcontroller systems makes it a reliable choice for learners and seasoned makers alike. Product specs at a glance
- Rated voltage: DC 5V
- Type: 4-phase unipolar step motor with gear reduction
- Reduction ratio: 1/64
- Step angle: 5.625° (motor), output angle ~0.0879° with gearing
- Output torque: pull-in > 34.3 mN·m; detent > 34.3 mN·m
- No-load frequencies: pull-in > 600 Hz; pull-out > 1000 Hz
- DC resistance: 200 Ω ±7% (25°C)
- Insulation resistance: > 10 MΩ (500 V)
- Dielectric strength: 600 V AC / 1 mA / 1 s
- Noise: < 40 dB (120 Hz, no-load, 10 cm)
- Operating temperature: -40°C to +85°C
- Board footprint: approximately 29 × 21 mm This combination of compact size, precise gearing, robust electrical specifications, and Arduino-friendly wiring makes the 28BYJ-48 with ULN2003 driver an essential building block for hands-on motion control, automation, and learning projects. Add it to your toolkit and start turning ideas into repeatable, measurable motion.
