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\n- 5V DC operation with a 4-phase unipolar design: simple, widely compatible with Arduino, Raspberry Pi GPIO, and other microcontrollers\n- 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\n- Built-in ULN2003 driver compatibility: wire directly to the driver board and drive with standard step pulse signals\n- Durable electrical specs: coil resistance around 200 Ω ±7% (25°C); insulation resistance \u0026gt;10 MΩ (500V); dielectric strength 600V AC \/ 1 mA \/ 1 s\n- Wide operating temperature: -40°C to +85°C, suitable for varied hobby and educational environments\n- Measured performance thresholds: no-load pull-in frequency \u0026gt; 600 Hz; no-load pull-out frequency \u0026gt; 1000 Hz; pull-in torque \u0026gt; 34.3 mN·m (120 Hz); detent torque \u0026gt; 34.3 mN·m\n- 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\n- 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.\n- 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.\n- 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\n- Robotics: create a compact rover or robotic arm with precise micro-positioning for grippers or sensors.\n- Camera and light control: build a tiny tilt\/shake mechanism for time-lapse photography or stage lighting with repeatable presets.\n- Educational kits: teach stepper motor fundamentals, torque, gear ratios, and motion control using real hardware and hands-on labs.\n- 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\n- Convenience: the ULN2003 driver board is integrated into the ecosystem, reducing the guesswork around drive electronics and wiring.\n- 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.\n- Proven compatibility: proven success with 5V microcontroller systems makes it a reliable choice for learners and seasoned makers alike. Product specs at a glance\n- Rated voltage: DC 5V\n- Type: 4-phase unipolar step motor with gear reduction\n- Reduction ratio: 1\/64\n- Step angle: 5.625° (motor), output angle ~0.0879° with gearing\n- Output torque: pull-in \u0026gt; 34.3 mN·m; detent \u0026gt; 34.3 mN·m\n- No-load frequencies: pull-in \u0026gt; 600 Hz; pull-out \u0026gt; 1000 Hz\n- DC resistance: 200 Ω ±7% (25°C)\n- Insulation resistance: \u0026gt; 10 MΩ (500 V)\n- Dielectric strength: 600 V AC \/ 1 mA \/ 1 s\n- Noise: \u0026lt; 40 dB (120 Hz, no-load, 10 cm)\n- Operating temperature: -40°C to +85°C\n- 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.
