Compact, precise linear motion for small electronics and DIY camera projects. This 5MM Precision Screw Slider Stepper is a 2‑phase, 4‑wire stepper assembly with an integrated planetary gearbox and moving block — designed for controlled, repeatable micro‑positioning and electronic starter applications. Key benefits Precision linear control: the 5MM precision screw slider converts rotary stepper motion into accurate, repeatable linear travel for fine adjustments. Improved torque and resolution: the built‑in planetary gearbox increases effective torque and enables finer incremental positioning for demanding micro‑movement tasks. Simple drive and control: the 2‑phase, 4‑wire stepper interface is compatible with standard stepper drivers and controllers, making integration into electronics and prototypes straightforward. Compact moving block: the slider (moving block) provides a stable platform for mounting small components or assemblies while preserving smooth linear movement. Ideal for DIY and electronics projects: designed to be used in small devices such as phone camera rigs, focusing mechanisms, and other compact automation tasks. Key attributes Functionality: Rotarytolinear conversion via a 5MM precision screw coupled to a stepper motor with planetary gearbox and moving block for controlled linear travel. Electrical interface: 2‑phase, 4‑wire stepper configuration — compatible with common stepper drivers and controllers that support 2‑phase motors. Mechanical drive: Planetary gearbox integrated with the stepper for higher torque and improved positioning resolution. Size note: Features a 5MM precision screw slider (as specified) and a compact moving block suitable for small form‑factor projects. Performance behavior: Designed for smooth incremental motion, repeatable positioning, and reliable actuation in compact assemblies. Compatibility and integration Works with standard 2‑phase stepper driver boards and controller firmware that accept 4‑wire stepper motors (wiring and drive settings per your driver). Mount the moving block to your structure or component and connect the stepper wiring to a compatible driver for straightforward control of linear travel. Suitable for battery or bench power solutions commonly used with small stepper setups — configure current and microstepping on your driver to match project needs. Typical use cases DIY phone camera focus/slider: Create a compact, motorized focus or micro‑slider mechanism for phone camera rigs, allowing precise, programmable adjustments for photography and videography. Small automation and prototyping: Add precise linear actuation to prototypes, desktop automation, or instrumentation where space is limited and fine positioning is required. Miniature robotics and model making: Drive small linear stages, repeatable positioning mechanisms, or adjustable mounts in hobby robotics and scale modeling projects. Practical notes Verify driver compatibility and wiring before powering the motor. The 2‑phase, 4‑wire interface requires a suitable stepper driver and correct step/dir wiring. Adjust driver current and microstepping to balance speed, torque, and noise according to your application. Mount the moving block securely to maintain alignment and preserve precision motion over repeated cycles. This component brings compact, repeatable linear motion to tight spaces and precision projects — particularly suited to DIY phone camera applications and other small devices that need controlled, fine movement.
