Description

Key Features:

✔ Stable Red Dot Output – 650nm wavelength, 5mW Class IIIA laser (safe for brief exposure).
✔ 5V DC Power – Directly compatible with Arduino, ESP32, and other 5V microcontrollers.
✔ Adjustable Focus – Twist the lens to sharpen the dot or widen into a line (focusable design).
✔ Compact & Durable – Small cylindrical housing (≈12mm diameter) with a brass or aluminum body.
✔ Low Power Draw – Consumes ~30mA, ideal for battery-powered applications.
✔ Instant On/Off – Toggle via digital signal or PWM for brightness control.

Applications:

• Precision Alignment – Leveling tools, construction guides, or woodworking jigs.

• CNC & 3D Printers – Bed leveling assist or engraving alignment.

• Educational Demos – Light physics experiments, optics labs, or laser tripwire alarms.

• Targeting Systems – Toy guns, robotics, or drone landing markers.

• DIY Light Effects – Laser harps, stage props, or interactive art.

Package Includes:

• 1 × 5mW Red Dot Laser Module (5V)

• (May include connecting wires or mounting hardware – check seller details)

How to Use:

1. Power Connection – Connect +5V and GND to your circuit (Arduino/RPi).

2. Control Signal – Wire the input to a digital/PWM pin for ON/OFF or dimming.

3. Adjust Focus – Rotate the lens head to refine the dot’s sharpness or shape.

Safety Warning:

⚠ Class IIIA Laser – Avoid direct eye exposure or reflective surfaces. Not for high-power applications.

Why Choose This Laser?

✅ Dot Shape Clarity – Sharper than line lasers for precise pointing.
✅ Plug-and-Play – No extra drivers needed (built-in current regulation).
✅ Versatile Mounting – Fits into holders, enclosures, or DIY frames.
