Overview

The 650nm 5V Red Laser Diode Module is a compact, breadboard-friendly laser module designed for electronics prototyping, robotics, positioning, alignment, and educational projects. The module combines a red laser diode, condenser lens, and adjustable copper sleeve in a pre-assembled housing.

It can be operated from a low-voltage DC supply and includes a control input that can be used with a compatible microcontroller. When used with Arduino or similar development boards, the control signal can be used to switch the laser on and off.

With a 650nm red laser wavelength and compact construction, this module is suitable for DIY laser experiments, robotic positioning systems, alignment tools, level-meter projects, laser-based signaling, and other non-hazardous prototype applications.

Laser safety is essential: never look directly into the beam, point it toward people or animals, or use reflective surfaces in a way that could redirect the beam into someone's eyes. Keep the module away from children and use appropriate precautions during testing.

Important Safety Information

This is a laser device and must be handled responsibly. Never look directly into the laser beam, even briefly. Do not point the beam at people, animals, aircraft, vehicles, or reflective surfaces that may redirect the beam unexpectedly.

Keep the module away from children. Use appropriate eye and beam-safety precautions during development and testing.

Also avoid short-circuiting the power connections or battery supply, as excessive current can damage the module or power source.

Note: The supplied source information contains differing dimensional and electrical descriptions. Specifications can vary between module batches, so verify the actual module markings and electrical characteristics before permanent installation.
