1.Product Introduction

The laser module is composed of a 650nm red laser diode head, driving circuit and three male pins, whose role is to generate a red dot shaped laser beam. It should be noted that the laser has powerful energy and highly concentrated beam, laser beam will cause damage to the human eye, do not directly illuminate the laser eyes.

Application reference: This module can be used in laser alarm, laser sight, smart home, etc.
