KY-008 5V 650nm Red Dot Laser Transmitter Module

Product Description

The KY-008 Module is a "plug-and-play" laser solution featuring a 6mm brass laser head mounted on a standard PCB. The brass head acts as a small heat sink and allows for minor manual focal adjustments by turning the front lens. Its 3-pin interface (GND, VCC, Signal) is designed for direct connection to microcontrollers like Arduino. When the signal pin is pulled HIGH, the laser activates instantly. Its low current draw (under 40mA) ensures it can be powered directly from a digital I/O pin without the need for an external driver or transistor.

Key Features

• Focused Precision: Produces a small, bright red dot that remains visible even at distances of 10+ meters in low-light environments.

• Instant Triggering: High-speed response time makes it suitable for pulsed data transmission or rapid-fire security sensors.

• Brass Housing: Provides mechanical protection for the delicate laser diode and aids in thermal dissipation during extended use.

• Easy Mounting: The PCB includes a 3mm mounting hole, allowing for rigid attachment to a robot chassis or a stationary tripod.

• Standard 5V Logic: No special power supplies required; it works seamlessly with the standard 5V rail of most development boards.

Technical Details

• Laser Class: Class IIIa (standard for hobbyist modules).

• Connector: 2.54mm pitch headers.

• Pinout: "S" (Signal/5V), Middle (No Connection/5V), "-" (GND).
