Frequently asked questions
Can I drive this module directly from an Arduino pin?
No. Laser diodes are sensitive to current and can be damaged if connected straight to a pin. Use a laser driver circuit or a module with built-in regulation, and confirm the supply voltage on the module label.
Is this laser safe for eyes?
Do not stare into the beam or aim it at people, animals or reflective surfaces. Even a small dot can cause eye injury at close range, so keep the beam away from eye level.
