Frequently asked questions
Can I power this 3V laser module from a 5V supply?
Not directly. This module is rated for 3 VDC, so connecting it to 5 V can exceed its rating and damage it. Use a regulated 3 V supply, or a series resistor or regulator as recommended in the datasheet.
What is the difference between this and the 5V version?
Both produce 650 nm red dot output at 5 mW with the same housing size. The main difference is the working voltage, 3 V DC here and 5 V DC in the other module, so choose the one that matches your power supply.
