With its short effective range this laser module is suitable for indoor applications. Perfect as an alignment reference marker. Red line should be connected to positive voltage supply and black line should be connected to negative supply. Do not apply overvoltage. Usually DC 5V is good to operate
No instructions. two of the ordered items were off-focus and I could not change focusing. The special optical lens ring can not be detached. My $6 is gone to garbage...
This module can be used in many applications. Although you are limited with your imagination They can be used in leveling meters and as alignment markers
Pricy for its built quality. The only important thing is the special lend in front of it. It is similar to laser pointers in other ways. And they are much cheaper (half the price) So the lens does matter as a conclusion
