The 5V 650nm Red Dot Laser Module is a compact and reliable laser diode designed for electronics projects, positioning systems, alignment tools, and DIY experiments. This small laser module contains a red laser diode with a collimating glass lens, producing a bright and focused red dot.
It includes a built-in resistor, allowing easy operation with a 3V–5V power supply. Simply connect it to a compatible voltage source and it will work instantly. The adjustable focus lens allows precise beam adjustment, making it ideal for Arduino projects, robotics, and optical experiments.
This lightweight and compact laser head is perfect for engineers, hobbyists, and makers looking for a reliable and affordable laser module.
Note: Never look directly into the laser beam and avoid pointing the laser at people, animals, vehicles, or aircraft.
