Laser Red Dot Module — 650nm, 5mW, Continuous Output

Laser Red Dot Module — 650nm, 5mW, Continuous Output for Arduino & DIY Projects

The 650nm red laser dot module projects a precise, focused red laser dot — the fundamental component for targeting, pointing, distance sensing, and laser-based detection applications. At 5mW output power and 650nm wavelength (visible red), this module produces a clearly visible red dot in normal indoor lighting conditions, making it ideal for Arduino laser projects, laser tripwire systems, and optical sensing applications.

The compact module format with standard 3-pin interface (VCC, GND, Signal) makes it easy to integrate into Arduino and microcontroller projects. The continuous output mode ensures a stable, consistent dot position for precision applications.
