The Open Smart 5V 650nm Laser Sensor Module is a compact and efficient red laser diode module designed for electronics enthusiasts, hobbyists, and embedded system developers. Featuring a 6mm copper head and an integrated triode current amplifier circuit, this module ensures stable and reliable operation while maintaining compatibility with a wide range of microcontrollers, including Arduino, ESP32, and STM32 boards. With only 1.3mA drawn from the signal (SIG) pin, it supports low-power applications without overloading your MCU. Operating at 4.75–5.5V, the module provides a bright 650nm red laser dot for applications such as positioning, alignment, DIY robotics, and sensor triggering. Its compact size makes it easy to integrate into projects, while the copper head provides durability and heat dissipation. For safety, avoid direct exposure of the laser beam to human eyes or prolonged irradiation of the body. Featured By RoboticsBD.
