Add optical targeting, distance detection, or laser security capabilities to your embedded projects with the 650nm 5V Red Laser Diode Transmitter Module. Built with a durable copper diode housing and a built-in current-limiting resistor, this module provides a focused red laser beam at a 650nm wavelength.
Designed for easy integration, it operates directly off a 5V DC power supply or digital microcontroller GPIO pins (via transistor/relay or direct drive depending on current draw). Whether you are constructing a DIY laser tripwire alarm, an optical barcode scanner prototype, or a laser-guided obstacle detection system, this module offers reliable performance in a tiny form factor.
