13x23mm 20mW/3V 555nm Yellow-Green Laser Diode Module

This is a compact and rare light green laser module.
The drive circuit and wiring are already completed.

It was purchased for repairing electronic equipment at my company, but the specifications of the original equipment no longer match, so I am selling it as part of asset liquidation.

Recommended for repairing electronic components, laser sights for guns, and various experiments.
*As this is a component, some technical skill is required for implementation and wiring.
(Basic soldering skills and understanding of voltage/current are necessary)

There are scratches and dirt from the manufacturing/storage stages.
