445nm 3.5W 4.75W High Power Laser Module TTL Modulation Laser Engraving Fingerprint Detection

445nm 3.5W 4.75W High Power Laser Module TTL Modulation Laser Engraving Fingerprint Detection

This laser module is not equipped with a power supply by default. Users only need to connect a 12V power supply to work and emit laser light. This product has no time limit and can be turned on for a long time. It comes with a fan for cooling, and the circuit board is separated from the host.
