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).

Applications:

• CNC/Laser Engraving – Low-power marking or alignment guide.

• Robotics & Drones – Target tracking or obstacle detection.

• Alignment Tools – Leveling, straight-line reference for construction.

• Educational Projects – Light sensors, burglar alarms, or science demos.

• DIY Light Shows – Sync with music or motion (using mirrors/galvos).

Package Includes:

• 1 × 5V Laser Diode Module (with wires or pre-soldered pins)

• (May include mounting clips or screws – check seller details)

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.
