Overview

Product Overview

The ShillehTek 6mm 650nm 5mW Red Laser Diode Module is a compact red laser emitter for Arduino and Raspberry Pi projects that need a visible, focused beam for alignment, tripwire style detection, pointing, and optics demos. It is commonly used with photodiodes or LDR sensors to build simple beam-break alarms, positioning guides, and basic robotics alignment tools. With a standard module form factor, it is easy to mount in enclosures or brackets and control from a microcontroller using a GPIO pin and proper current limiting.

Questions & answers

Frequently asked questions

Yes. It is intended for Arduino and Raspberry Pi projects where a visible 650nm red beam is controlled by a microcontroller. Use an appropriate driver or switching circuit instead of relying on a GPIO pin alone.
No. It is supplied as a compact module, so you do not need to assemble a bare laser diode circuit. You still need to mount it securely, verify polarity, and provide proper current limiting before powering it.
This module is for 5V projects and emits a 650nm, 5mW red beam. Control it as a switched load from a microcontroller output using proper current limiting and a suitable transistor or driver when needed.
Yes. Aim the laser at a photodiode or LDR sensor and monitor the receiver with a microcontroller. When an object blocks the beam, your code can trigger an alarm, counter, positioning check, or robotics action.
It can be used indoors for projects, but it is still a laser. Never stare into the beam, avoid reflective surfaces that can redirect it into eyes, and use supervision and appropriate precautions during demos.
