Laser Diode Module 5mW 650nm 5V Red

Laser Diode Module 5mW 650nm 5V Red 

The 5mW 650nm Red Laser Diode Module is a compact, low-power red laser emitter commonly used for alignment, pointing, measurement, and DIY electronic projects. It produces a bright red laser beam (650nm wavelength) and operates from a standard 5V supply, making it easy to interface with microcontrollers such as Arduino, ESP32, Raspberry Pi, and other embedded systems.

The module typically includes:

• A laser diode
• Built-in current-limiting driver circuitry
• Collimating lens for focusing the beam
• Three-pin interface (VCC, GND, Signal)

It can be controlled using digital pins and is suitable for indoor and short-range optical applications.
