Description

Key Features:

✔ 5V DC Operation – Works seamlessly with Arduino, ESP8266, and other 5V microcontrollers.
✔ Visible Red Laser – 650nm wavelength (Class IIIA, <5mW power) – bright and eye-safe for indoor use.
✔ Adjustable Focus – Twist-to-focus lens for sharp dots or fine lines.
✔ Compact & Lightweight – Small form factor (typically φ12mm × 30mm) for easy mounting.
✔ Low Power Consumption – Draws ~30mA, suitable for battery-powered projects.
✔ Fast Response Time – Instantly toggles ON/OFF via digital signal (PWM compatible).

How It Works:

1. 1. Connect to Power – Wire +5V and GND to your MCU or PSU.

   2. Control via PWM/Digital Pin – Use Arduino’s digitalWrite() or analogWrite() for brightness control.

   3. Adjust Focus – Rotate the lens head for desired beam sharpness.
