3V Flexible LED Strip (138 LEDs) is an ultra‑slim lighting solution designed for projects where installation space is extremely limited. Measuring only 2.5mm in width and 1mm in thickness, this miniature flexible light strip fits easily into narrow structures, model assemblies, and compact electronic builds. Operating at a low 3V supply, the narrow LED ribbon pairs well with compact controllers such as FireBeetle and Arduino. A dense arrangement of 138 LEDs per meter delivers continuous and uniform warm white illumination while maintaining low power consumption for embedded electronics, miniature robotics, and decorative lighting builds.
Ultra‑Slim Structure for Tight Installation Spaces
This flexible LED lighting strip features a remarkably thin profile of just 2.5mm wide and 1mm thick, enabling integration into places where conventional LED strips cannot fit. The compact form factor suits narrow grooves, miniature architectural models, small toys, and precision decorative builds. Flexible construction allows easy routing around curves and edges without damaging the circuitry, making this narrow illumination strip especially practical for detailed model work and compact embedded lighting systems.
Low‑Voltage Operation for Embedded Electronics
Designed for 3V operation, this low‑power LED ribbon integrates smoothly with common maker controllers and battery‑powered systems. Compatibility with development boards such as FireBeetle and Arduino makes the lighting module suitable for robotics lighting effects, portable electronics, and experimental prototypes. Low voltage requirements also simplify power management in small devices, supporting safe operation within compact DIY electronics or mobile robotic platforms.
High LED Density with Individual Cut Capability
A density of 138 SMD 0805 LEDs per meter provides smooth, evenly distributed warm white illumination without noticeable dark gaps. Each LED segment can be cut individually, allowing custom lengths tailored to specific project layouts. This precise cutting capability enables builders to design miniature lighting circuits, compact decorative panels, and tightly fitted illumination paths while minimizing material waste.
This ultra‑narrow LED lighting module suits decorative illumination, miniature engineering builds, and educational maker projects. Typical uses include sand table scenery, architectural models, DIY light panels, toy lighting systems, and smart robotics vehicles requiring lightweight integrated lighting. Compact dimensions and low power operation make the flexible strip an effective lighting component for creative electronics and STEM project development.
