The module is housed in a compact metal casing with a diameter of 6 mm and is connected via two soldered connection wires approximately 5 cm long. The red wire is positive, and the black wire is ground.\u003c\/p\u003e \u003cp\u003eBecause the laser diode is already equipped with a series resistor, it can be connected directly to a 5 V DC power source. An Arduino or other 5 V board can control it directly by connecting the positive terminal to the power supply and the negative terminal to ground. This eliminates the need for separate driver electronics.\u003c\/p\u003e \u003cp\u003eThe laser diode is suitable for laser barriers in combination with suitable receiver components, optical alignment aids, and educational projects in optoelectronics.
