Laser Module Emitter – Red Line cc3000 No jumpers neededIntroduction : Device parts Length: 23mm line Operating voltage: 4. 5 V 51 Resistance In the ideal case (no dust, no fumes, no barrier), the laser transmission distance is infinite. In general, cloudy night, exposure to 500 meters away from objects, it is clearly visible; For a closer distance, even in the sun of the day, shone on the pavement,outside the building,it is also clearly visible. Application: production of electronic pointer pens,
