Green 532nm 100mW Laser Diode Module Fat Dot 12V TTL – Elubor

Elubor 532nm Green Laser Diode Module – Fat Dot, 100mW, 12V TTL

Bring precision and vivid green illumination to your stage, DJ setup, laboratory, or custom electronics project with the Elubor 532MD-100-12V Green Laser Diode Module. Emitting a bold 532nm green wavelength at 100mW output power, this compact module delivers a wide-angle fat dot beam — perfect for applications that demand a large, visible laser spot rather than a tight pinpoint. Built-in TTL control (0–5V, 0–20kHz) makes it easy to integrate with microcontrollers, signal generators, or professional lighting controllers for dynamic, modulated effects.

Frequently Asked Questions

Q: What does "TTL modulation" mean on this green laser diode module?

A: TTL (Transistor-Transistor Logic) modulation allows you to switch the laser on and off rapidly using a 0–5V digital signal at frequencies up to 20kHz. This makes the Elubor 532nm laser module compatible with microcontrollers (Arduino, Raspberry Pi, etc.), signal generators, and professional lighting control systems for strobing, pulsing, or pattern-based laser effects.

Q: What is the difference between a "fat dot" beam and a standard laser dot?

A: A standard laser module produces a very tight, narrow beam spot. This module is specifically designed to emit a wide, coarse dot — approximately 15–16mm in beam diameter — making it ideal for stage and lighting applications where a large, bold visible spot is desired rather than a pinpoint.

Q: Does this laser module require an external driver or power supply?

A: No — the Elubor 532MD-100-12V is a self-contained module with a built-in 12V DC driver. Simply connect a 10–12V DC power supply (red wire positive, black wire negative) and it is ready to operate. No external driver board is needed. Note: batteries are not included.

Q: Is this module suitable for outdoor use?

A: This module is rated for operating temperatures of +10°C to +30°C and is designed primarily for indoor professional stage, DJ, and electronics use. Extended outdoor use in humid, dusty, or extreme temperature environments is not recommended without additional protective housing.
