This compact laser diode module provides a 1 mW laser source for electronics projects, alignment tools and sensor applications.
It operates from a wide 2.6–5 V input range, making it suitable for use with both 3.3 V and 5 V microcontroller systems, including Arduino-style experiments.
Package includes 1× 1 mW laser diode module.
Specifications:
- Output Power: 1 mW
- Input Voltage: 2.6–5 V
- Current Rating: 40 mA
Ideal for laser tripwire and security projects, alignment and positioning tools, sensor and detection circuits, and microcontroller experiments. Never point a laser at people, animals, or reflective surfaces, and avoid direct eye exposure.
Jargon buster
Plain-language definitions for the technical terms used above.
- laser diode
- A semiconductor component that produces a narrow beam of laser light when electrical current flows through it. Laser diodes often need current control and safe handling because too much current can damage them and the light can be hazardous to eyes.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
