LASER MODULE

The Laser Module is a compact 650nm red dot laser emitter with built-in APC (Automatic Power Control) circuit, condenser lens, and adjustable copper sleeve. Pre-assembled and pre-focused. Connects directly to 5V DC. Control pin (S) HIGH turns laser ON. Suitable for Arduino, Raspberry Pi, and general DIY/robotics applications.

⚠ Caution: Never look directly into the laser beam. Avoid pointing at eyes or reflective surfaces.

Pin Configuration:

• GND — Ground
• VCC (5V) — Power supply
• S — Signal (HIGH = laser ON)

Specifications:

• Supply Voltage: 3.0–5V
• Operating Current: 40mA
• Transmit Power: 58mW
• Driver: APC circuit
• Cable Length: ~135mm

Applications:

• Laser ranging and alignment tools
• Concentricity and level positioning
• Robotics and obstacle detection
• DIY laser projector and toys
