520nm Green Line Laser Module, 5mW, 3–5V DC, 90°

The 520nm Green Line Laser Module is a compact, high-visibility semiconductor diode laser designed for precision positioning, alignment, and robotics. It projects a bright 90° green laser line while operating efficiently from a 3V to 5V DC power supply. This makes it an ideal component for makers, students, and hobbyists building visual alignment systems with Arduino, ESP32, or Raspberry Pi.

High-visibility optical output

Featuring a 520nm semiconductor diode with an optical output power of up to 5mW, this module produces a crisp, clear line. The integrated optics provide a 90° fan angle for broad line projection.

Microcontroller compatible power

The module is powered via a 3V to 5V DC supply and draws between 20mA and 60mA of current. This low-voltage requirement allows straightforward integration with common development boards like ESP32, Raspberry Pi, and Arduino.

Robotics and alignment applications

With a compact form factor and an operating temperature range of 10°C to +50°C, the module is suited for DIY laser levels, machine vision setups, and robotic guidance. It is engineered for versatile use in automation, DIY electronics, and positioning tasks.
