The 650nm mini laser dot diode module emits a focused red dot at 650nm wavelength (the red portion of visible light) with 5mW output power. At just 6mm in diameter, the mini laser dot module fits inside drilled holes in enclosures, project boxes, and 3D-printed parts with ease. Connect the 120mm leads to a 5V supply at 40mA and the dot appears instantly.
One honest limitation is that the 5mW dot laser output is stronger than decorative pointer lasers, so avoid pointing it at eyes or reflective surfaces near face level. Students and robotics makers use this dot laser light for beam-break sensors and target detection builds. Wire red to 5V and black to GND. StemVolt provides this sensor with trusted quality, ensuring reliable performance and easy usability.
